Ansys CFX: Flow Around a Blunt Body (tutorial)

In this tutorial, a generic vehicle body is placed into an oncoming side wind of 15 m/s. The turbulence will be set to Intensity and Length scale with a value of 0.05, which corresponds to 5% turbulence, a medium level intensity, and with an Eddy Length scale value of 0.1 m.

The goal of this tutorial is to accurately model the behavior of the flow around the body. Since both the geometry and the flow are symmetric about a vertical plane, only half of the geometry will be used to find the CFD solution. The overall approach to solving this problem is to first set the free-slip wall boundaries on the sides of and above the domain. The near-wall flow will then be modeled using Shear Stress Transport. Vector plots will finally be created to display the near wall low behavior.
