Analisa Pola Aliran Bodi Mobil Esemka Rajawali Standar Dengan Esemka Rajawali Modifikasi Menggunakan CFD (Computional Fluid Dynamic) Pada Software Ansys 15.0

Abstract

One development in a car is a car body design . Car design factor not only in terms of aesthetics ( beauty ) , but also by the shape of its body aerodynamics . Thesis research aims to determine differences in the flow pattern , the coefficient of drag ( CD ) and the lift coefficient ( CL ) on the car body with a standard ESEMKA RAJAWALI and ESEMKA RAJAWALI car body modifications. This research was done by changing the geometry of the corner of the hood with glass body with a standard car into a 156o angle of 165o , and change the front bumper has become a 90o angle 65o . Manufacture of car body design using SolidWorks 2014 software and simulated using the software Ansys CFD 15.0 CFD simulation results obtained from differences in patterns of flow and pressure values on each car body car body . Based on the results of the simulation calculations drag coefficient and lift coefficient on the car body modification ESEMKA RAJAWALI smaller than standard ESEMKA RAJAWALI car bod
