Ansys-CFX Analysis on a Simple Automobile Design

Roopsandeep Bammidi | Dr. B. V.Ramana Murty

Abstract: Aerodynamics is the study of the effects of air when in motion. The vehicle aerodynamics have become crucial since have realized its importance The physical appearance of the car has been given keen significance while designing the external devices. Aerodynamics drag was considered for giving a better efficiency on the road. The analysis was done for the simple automobile design at a speed of 60km/h. The technique to estimate the drag is by using input of Catia part modeling and exporting it to Ansys CFX to find the value of aerodynamics drag in terms drag coefficient. The result shows that such as contours; vectors turbulence kinetic energy and also used to analyze the characteristics of streamlines flow or boundary layer that occurs on the body of this model. All the analysis and modifications have been carried out computationally in the CFD software ANSYS Fluent 15 and the part modeling in CATIA V5R19.

Keywords: modeling, Ansys-cfx, FEM, contours, vectors and drag coefficient
