As the performance of a catalytic converter is substantially affected by the flow distribution inside the substrate, a uniform flow distribution can increase its efficiency, lower the pressure drop and optimize engine performance. The flow distribution in a catalytic converter assembly is governed by the geometry configurations of inlet and outlet cone section, the substrate and exhaust gas compositions and therefore a better design of the catalytic converter is very important. In this blog we shall have insights of CFD modeling approach of flow inside a catalytic converter with the help a flow visualization.

In the earlier blog Combustion in Internal Combustion (IC) Engines we had an introduction about the combustion phenomena taking place in an automotive IC engine. The present article is an effort in continuation to have insights on CFD of combustion in IC engines. As we know the key factors that govern the decision making of any automobile buyer in general are, its mileage, performance, maintenance and tentative life apart from passenger comfort and aesthetics. An engine forms the heart of an automobile that can dictate its performance and life and is solely governed by the combustion pattern inside. The detail analysis of combustion in any engine is one of the most important key factors to confirm its efficient design wherein computational fluid dynamics (CFD) proves to be an efficient tool.

Applied Math Modeling Inc, a provider of application specific CFD simulation solutions is partnering with Centre for Computational Technologies (CCTech), a leading provider of software product development, premium consultant services and education in the CAD, CFD and PLM markets. Applied Math Modeling Inc and CCTech will partner to provide CFD application training through LearnCAx, the global CAx education wing of CCTech. Through the partnership, Applied Math Modeling Inc will support registered students at LearnCAx with free* software access to the CoolSim application for a 9 weeks period.

Grid generation or meshing is a very critical part within the CFD simulation process as it not only dictates the simulation time but also the accuracy of results of the study. Generating a very coarse and poor quality mesh/ grid often leads to non-physical or highly inaccurate simulation results though may be solved on a very powerful solver. Hence the grid generation skills, capability and its exposure are of equal importance as much as that of the solver operations.

Recently there has been great interest by design engineers/ CFD analysts/ researchers worldwide to develop greater insights in the design and performance analysis of Turbiomachinery as they form an important component in major industrial applications. The blog aims to provide an overview of Turbomachinery and the essential CAD cleanup steps while meshing turbomachines for CFD analysis with the help of a software video demonstration on a commercial tool.
