Computational Fluid Dynamics (CFD) is a technique of studying fluid flow, heat transfer, chemical reactions and related phenomena using mathematical equations which govern these processes. The equations are solved using numerical methods on high performance computers. The result of CFD analysis is engineering field data (such as flow and temperature distribution, distribution of stresses, gradients etc.). The results can be used to study new product and process concepts, trouble shooting and performance comparison. CFD analysis is complementary to physical testing and experimentation. It reduces the total effort required in the laboratory. However, the experimentation can never be completely eliminated.

We work with the clients to understand their engineering processes and the areas where design modifications could be done to increase the efficiency/performance of the process. Our first step is to reproduce the observations of client through CFD simulations and additional calculations, if required. In this step we convert the physical process details into simulations by making appropriate approximations, if needed, to make the model as close to real as possible. A modeling approach is devised and applied to perform simulations and obtain the results to compare them with the observations in actual process.

The following modeling approach is pursued:

Once the simulations capture the physics appropriately, multiple design modifications are evaluated. Based on results of the simulations our understanding and sensitivity of different parameters on the performance is conveyed to the client.

A couple of design modifications which could enhance the performance of the process is suggested and backed with the results.
