In this session we will introduce industry specific applications from the aerospace industry and how Computational Fluid Dynamics (CFD) is used to solve problems and optimize subsystems. We will begin our discussion with the analysis of flow over an aircraft wing. Then, we will use switch gears and understand how aircraft engines generate thrust by analyzing the flow through a converging nozzle. We will then discuss regarding high-lift devices by studying the flow over a multi-element airfoil. Finally, we will wrap up by looking at an example to understand the physics of high speed airflow over an aircraft wing section which is significantly influenced by the compressible nature of air.
