Abstract |
|
The aerodynamic performances of the Ahmed body is explored statistically using ANSA software for pre-processing and for post processing and solving ANSYS FLUENT software and in the learning the K-Ô‘ (k-epsilon) turbulent model is recycled in demand to decrease at computational price at extraordinary Reynolds number. In the following analysis the four configurations with slant angle of 100, 200, 300 & 400 are measured. The correlation between aerodynamic drag and rear diffuser angle is precised and flow apparatus are evaluated and discoursed. In the explored the completely established turbulent flow in excess of Ahmed body and evaluate the effect of slant angle, four separate cases have been solved for different slant angle and results are compared. The results understand the better lift and drag for a body. |
