External Flow Analysis over Hyundai Model Using CFD
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2019, Vol 16, Issue 1
Abstract
Computational fluid dynamic software ANSYS Fluent 15.0 is used to predict the physical parameters on the external surface of a vehicle. The simulation of the wind tunnel experiments using the above CFD package would be carried out. To study the aerodynamic influence of vehicle segments are considered as threebox form passenger car Hyundai model. As this model provided with the extremities in the design of vehicle category in summarizes these results in a broader sense to understand the aerodynamics of such profile. A wind tunnel experiments consists of physically testing the model in a simulated environment. It is a closed environment in which air is blown across the model at a constant velocity. As the air passes over the vehicle, it follows the streamlines pattern present on the body. This causes a change in pressure and velocity characteristics across the model. By studying the pressure and velocity variations across the model, the drag and lift coefficient could be predicted.
