Abstract

A cooling system is one of the vital engine systems. It additionally increases heat transfer and fuel economy which indicates the performance of an engine. Most internal combustion engines are fluid cooled using either liquid or air coolant that runs through a heat exchanger (radiator) cooled by air: the engine radiator vent, a heat exchanger that removes heat from engine coolant that flows through it. However, the grille shaped of the radiator vent had resulted in a different inflow velocity that plays a crucial role in the airflow path, aerodynamic and cooling performance of the bus. It is due to the grille design on the radiator vent. Therefore, the aim of this study is to remodel the physical testing using Computer-Aided Design (CAD) and Computational Fluid Dynamics (CFD) software to analyze the airflow performance effect of grille shape on the engine radiator vent at the side of the bus and verifying the simulation results by using Altair HyperWorks software. There are 3 grille designs created from the benchmarks which are the14 sides, the 8 sides, and the horizontal design. The data that we simulate from the simulation are compared together. The expected results are discussed in term of grille design and better cooling performance. Thus the best design was the 8 sides grille facing the right side direction because it has the highest velocity magnitude value and the lowest engine temperature condition compared to the other grille designs.
