CFD simulation for in-depth understanding of complex systems

Computerized fluid dynamics numerically reproduces what is happening with a real system under investigation. If such a system is simple and one needs to clarify a simple hypothesis, sometimes it is easier and faster to manufacture several real-life prototypes and do the testing.

However, in most cases, the systems which have to be developed are complex and their behavior can not be understood without deep insights on what is happening with temperatures, deformations, how gas velocities are distributed in systems with time, how different mechanisms and physics are interlinked and influence each other. Sometimes it is not possible to physically reproduce required extreme testing conditions, and sometimes virtual testing is much cheaper compared to real-life experiments. In such a case, the only feasible way to proceed is to create a numerical model with a sufficiently deep description of a real system i.e., describing on a computer all necessary processes and properties that need to be understood to design fully functional and optimized products. The Digital model has to provide adequate accuracy, i.e., the validity of the digital model has to be confirmed by real-world testing and verification.

Computational fluid dynamics modeling at EnCata

Computational flow dynamics, which includes Thermodynamics & Heat Transfer Analysis, Structural & Thermal Analysis, is a more elaborated, compared to FEA, computational approach which is used by EnCata’s engineers. While FEA is routinely used by all mechanical engineers, CFD techniques are more specialized and require a deeper understanding of methodology, panel methods in computational fluid dynamics, post-processing, and skills in CFD software. For this reason, we have at EnCata a dedicated simulation group of engineers dealing with CFD projects. In most cases, our own in-house computational resources suffice for such calculations; if necessary, we employ research supercomputers of our partners.

Mechanical Engineering

EnCata helps develop products, which exist in real life and work in various environments. Principles of computational fluid dynamics help be sure that products are functional and safe. Our engineers carry out industrial structures analysis and heat transfer simulation in SolidWorks and other CFD software.

Enclosure Design

The enclosure is one of the most common objects for mechanical design. We prefer to work on enclosure design holistically.Heat transfer simulation is more efficient and insightful compared to 1D thermal calculations or 2D heat transfer finite element analysis in Matlab. It helps mechanical designers to understand the system better and prevent the overheating of electronics.

FEA and CFD simulations

Proof-of-Concept Prototyping

The proof-of-concept stage is a good start for new product development. The design of a proof-of-concept prototype is not a simple task, as it can seem at first glance. The key point here is prioritizing functions to be cost-effective. The POC prototype could be a good addition to fluid dynamics simulation.

Custom electronics design

Reverse Engineering (RE)

Using RE gives obvious benefits for any product design company. Since you are not reinventing the wheel during the design stage, you are both saving time and reducing costs. Fluid flow simulation could support RE and provide a better understanding of the system under review.

Firmware development

Feasibility Studies

It is important to understand what benefits new product features will give your business, as well as how this will affect the financial performance. Our engineers could conduct a technical analysis of competitors. Meanwhile, our product design consultants will calculate the preliminary financial indicators, so you can make informed decisions.

Product R&D

The use of computational fluid dynamics (CFD) when testing hypotheses and searching for non-standard solutions allows you to get new information about the object of research much faster. CFD flow analysis is used as a tool for fluid flow simulation and thermo-structural analysis.

Fluid flow modeling make the difference

Computational fluid analysis provides the data for cost-effective design, usage, and maintenance. It helps determine the optimal power of pumps and fans. Industrial structure loads could be optimized by using various CFD techniques.

This leads to a reduction in energy and raw materials' consumption.The computational fluid analysis also reduces risks of redesign and overengineering thanks to experimental data that could be collected almost online by thermodynamics and mechanics simulation.

System Optimization And Computational Fluid Dynamics Applications

Computational fluid dynamics in CFD software and CAD, like Solidworks, can be applied in a vast range of cases and scenarios. Here are just a couple of cases in EnCata where it would have been impossible to develop high-quality products without using CFD.
To optimize the fan blades experimentally, one would need to manufacture and test fans for multiple different blade curvature parameters, which is very expensive. Instead, we have chosen to employ CFD, which allows substituting real-life experiments with a parametric model. The developed model has been validated to ensure the new blade design indeed provides the best performance.

The shape of new blade profiles is described with three new parameters (angles), which allow describing significantly more different blade geometries compared to the approach used to design the fan with the initial blade design. The best new blade shape has then been obtained with help from an optimization tool that automatically obtains the optimal blade configuration by calculating the fan efficiency for different blade geometries. The new optimal blade shape made it possible to get rid of negative pressure zones with the stagnant flow on the pressure side of a blade. This increased the aerodynamic efficiency of the blade from 84% to 92%.

EnCata had to develop a rotary exhaust device for the removal of welding fumes from the working area. During development, in order to ensure maximum performance and norms-compliance of the whole device, it was necessary to make sure that the design of the exhaust socket allowed the minimum airflow to meet the requirements for flow rate at the distance from the socket, according to ISO 15012-2. A computational model of the basic socket structure was prepared, and virtual tests were carried out according to the ISO 15012-2 method using CFD modeling.

Thus, the basic shape of the hood was changed to a new one, requiring a lower minimum airflow rate to achieve the required speeds according to the standard. This modification made it possible to increase the efficiency of the welding aerosol extraction process i.e., improve the performance of the product, without creating intermediate prototypes in metal. Also, with the help of CFD modeling, the aerodynamic characteristic of the PVU was used, which is necessary to coordinate the operation of mobile filter ventilation units to which this device is connected to. 

Within another project, EnCata had to improve the aerodynamic efficiency of a radial fan. Clearly, the efficiency of a fan significantly depends on the blade shape. The blade shape for a given fan was chosen based on the experimental curves of the blade profile, which were taken from the classical fan’s design handbooks. The handbooks rely on the experimental dependencies of fans versus three-blade parameters (inlet and outlet angle, blade radius). More complicated blade shapes, which can not be described with these three parameters, were, therefore, not taken into account in the initial design of the fan that needed to be improved at EnCata.

FAQ related to Product development

IP ownership when working with EnCata

When working with our clients we sign a contract where all the intellectual property to be generated during the R&D and engineering development belongs to the customer.

Do you sign NDAs?

Yes. As a highly professional design and engineering firm, we make sure that all discussions with our clients and all information regarding your invention, idea and other proprietary information are kept confidential.

How do I make sure EnCata does not "steal" my idea?

Aside from being a reputable company which does not steal ideas, EnCata's entire business model is based on delivering premium R&D, design and industrial prototyping services to our clients. As soon as we stole one client’s idea, our entire business would be ruined. Also, as we are not contract manufacturers (OEM or ODM), we wouldn’t be able to benefit from a stolen idea even if we wanted to.  This is definitely not a worry for our clients.

Patent or Develop first?

We follow a LEAN approach in product and business development and thus we strongly recommend patent filings only after you are  at least part-way through development. This is because patenting is expensive and early patents can already become obsolete or irrelevant later in the development phase. Typically, EnCata's work generates many patentable opportunities for our clients  and the best strategy is to file patents at TRL-7, i.e. when early beta prototype is ready and when a startup is ready to start batch production and marketing.

There is, however, another strategy, which is to use provisional patents which can be loose and are not to be disclosed to the public for 18 months. These are much less expensive and time consuming, generally costing below $500. EnCata will always sign a Non-Disclosure Agreement and keep your intellectual property confidential during the development phase and then we can recommend several third-party patent attorneys when the time is right.

Can EnCata consult me or help me with my existing design?

Whether you need to validate, evaluate or review your design, concept, 3D model, BOM or drawings, our experienced manufacturing, mechanical and electronics engineers are ready to help.

EnCata’s engineering consultancy service will allow you to critically reassess your project and help reach your goals while keeping the process cost-effective. To read more about the TRL and learn why it is useful, please procees to our blog.

What are typical project EnCata engaged with?

EnCata develops integrated Hardware and Software solutions for a variety of industries. We are engaged in multiple domains like IoT, robotics, medTech and IoMT, aerospace, agriculture, consumer products and many others. It is possible to work with such a wide variety of industries because we have multidomain expertise and utilize a cross-disciplinary product development approach.

I would like to do prototyping myself. Is it possible with EnCata?

Generally speaking, we do not allow clients to work on EnCata's manufacturing premises.

What does work, however, is that EnCata can manufacture prototype parts and the startup team can assemble thea prototype in our MakeIT Center hackerspace.  Alternatively, the startup can design and build the prototype themselves in our hackerspace.  We operate this free-access space in Minsk and we are currently working on expanding a hackerspace network worldwide.
