Abstract

3D-Simplified bus model (without wheels) is inspected at Reynolds number 2.19×106 (based on the length of bus and velocity inlet). A modification to increase the aerodynamics performance of vehicle is performed by using multiple-channel diffusers on the rear bus body. Diffuser angle (β) 12° is chosen as a constant variable. Two, Three and Four Channels are chosen as a variable. The results show that multiple channel diffuser can increase aerodynamics performance of the bus. Two channel produces optimal negative lift while Four channel produces optimal drag coefficient.
