Abstract

Lately, aerodynamics plays an important role while designing any automotive vehicle. Automotive industry has more interest in the aerodynamic shaping on road vehicles which is including cars, bus and trucks. This aerodynamic shape actually will influenced the airflow on the vehicle. Grille is a component that will allow air flow inside the underbody component and also act as cooling system. Usually grille for vehicle will be mounted on the front end of automobile but for bus it is located side and the back of the bus due to the position of the engine compartment that is located at the back that is different from cars and truck. It also acts as a protecting guard from any surrounding condition such as rain and protect it from rock and act as filter from dust. In this study, a Pioneer Coach Builder (PCB) bus model is considered and it is modelled using CATIA V5 software. Attention is only given to the external design that focus on intake grille shape of the bus, while the interior is not modelled. Therefore, this aim of this study is to redesign the intake grille shape using CATIA V5 software to investigate the airflow performance distribution on the intake grille and verifying the simulation result with the physical testing using wind tunnel data. Furthermore, Computational Fluid Dynamics (CFD) software is used as a simulation software in this study as the most cost effective solution for intake airflow analysis on the engine intake system.
