In this session we will introduce industry specific applications from the automotive industry and how Computational Fluid Dynamics (CFD) is used to solve problems and optimize subsystems. We will begin our discussion with the analysis of external aerodynamics of a concept car. Then we will use the power of computational fluid dynamics to uncover the role of streamlining in high speed rail transport. We will wrap up by looking at an example that deals with how we can use CFD to analyze internal sub-systems such as an IC engine exhaust manifold.
