In this project, simulation of air flow around vehicle side mirror had been investigated. The side mirror models that have been chosen for this research were models from the national car manufacturers. ANSYS FLUENT software was used to run the simulation. k-ε turbulent model is used to calculate flow around the vehicle model and make a comparison between all models at vehicle speed 25m/s (90km/h). The main objective of the research is to study and obtain the flow pattern around vehicle side mirror. Several factors that influence the flow pattern such as flow separation, the effect of pressure coefficient (Cp) and types of turbulent has been studies. Detail velocity variation and pressure distribution plots around the vehicle envelopes have been presented. Simulation and results of this study showed the airflow pattern for each selected national car model and the effect in terms of fuel efficiency had been discussed. Perodua Kenari shows higher pressure distribution compared to other models. Perodua Myvi show higher streamline velocity compared to other models
