In this session, we will introduce some industrial equipment involving the motion of fluids and learn to use the power of Computational Fluid Dynamics (CFD) to simulate them. First, we will learn about the fluid pressure drop in the flow through a stop valve using Ansys Fluent. We will use the power of simulations to understand the mechanism of how the cement industry uses the cyclone separator to separate the particles based on their size and mass. In addition to this, we will also model the airflow through an axial fan flow in Ansys Fluent. Finally, we will discuss the physics of heat exchangers, and learn how a shell and tube heat exchanger is used to cool transformer oil in hydro-electric power plants.
