Abstract
The customer needs are increasing day by day due to which the advance technology plays an important role in the automobile industry. At considerable speed, forces like drag & lift, weight, side forces and thrust acts on a vehicle which significantly affect the fuel consumption. The drag force is produced by relative motion between air and vehicle and about 60% of total drag is produced at the rear end. Reduction of drag force improves the fuel utilization. The drag force can be calculated by Experimental or Computational fluid dynamics (CFD) technique. Due to competitiveness in the market as well as high cost, time and other limitation. It can be advantageous to use CFD over traditional experimental-based analysis. The purpose of this work is to use CFD software for finding out drag, lift forces and other flow features at different velocities on Audi car profile. The velocities are 80, 100, 120 kmph. This study proposes an effective validation of results between experimental method and CFD methods. The software used in this work are Solidworks 2015 (Modelling), GAMBIT 2.4.6 (Meshing), ANSYS Fluent 17.0 (CFD Solver) as well as Tecplot 360 (Post Processing).
