Aerodynamic Analysis of Motion of Two Vehicles and Their Influence on Drag Coefficient

Aerodynamics is the study of influence of gases (mostly air) on moving bodies. In automobiles aerodynamics are responsible for lift and drag forces that become an obstacle in its motion. However , if properly controlled their effects can be minimized. This study gets even more interesting, when aerodynamic flow over one vehicle gets influenced by its neighbouring one. This project deals with the study of the influence of fast moving bus on a car. The main focus will be on the transition in the drag coefficient of the car at different speeds. Ansys software is used for simulating the situation. Meshing is done with the help of Ansys Mesh and fluent solver is used for simulation. The main focus will be on the transition of drag coefficient as a function of distance between bus and the car.
