External Aerodynamics Around a Sports Car

In this exercise, we will study the external flow aerodynamics around a sports car.

The car is located in a wind tunnel, and is subjected to 80 mph air flow. The model is cut in half and symmetry used to reduce the overall analysis size.

Key Topics

• External flow
• Incompressible, turbulent, steady state flow
• Mesh Refinement Region
• Symmetric geometry
• Particle trace models such as spheres, cylinders,and comets
• Wall Calculator for assessing flow-induced forces

Objectives

• Use velocity vectors to study flow
• Use particle traces to study the flow
• Measure the aerodynamically-induced forces on the surfaces of the car
