Investigation of drag coefficient at low velocity for front of two wheels vehicle based on CFD method
Keywords:
Two-Wheeler, Rider, CFD, Simulation, Coefficient of DragAbstract
Two wheels vehicles for city use are common in Asia and particularly in India. Two wheels vehicle is in large population because of affordability, efficiency and economic purposes. In the 10 to 20 years the market turned to bigger swept volumes vehicles such as 250 and 500 cc. This makes two wheels vehicle market richer and more adult, which needs a attractive design, comfort and stability at all speed. On the other hand, most of the vehicles for city uses at low velocities. For better performance of vehicles need more development of the engines and design makes two-wheeler aerodynamic characteristics analysis is much more necessary now. In this work, by using CFD method external flow field of a two wheels vehicle’s front is analysed including the driver. Summarized data and the computational results are obtained, including velocity field, pressure field, and coefficient of drag. This work will provide specific reference significance to the numerical simulation on motorcycle and motorcycle design on the future.
