Design and CFD Analysis of Bus Body

Human always believes in faster routine in their daily life. Considering road transport, buses are the major source for the road transport. If it is required to keep low operating costs, achieving the high fuel conversion efficiency at higher speeds is necessary. Hence the fuel efficiency become the major factor for the manufacturers Nowadays manufacturers in India are more concerned about aesthetic sense of bus. But after observing development of roads in India aerodynamics plays a vital role in reduction of travel time. The objective of this project is to check the behavior of exterior bus body with improved aerodynamic shape and focus on better fuel efficiency with aerodynamics structure. The existing design of bus has been developed with change in its shape so that the new design must attain aerodynamic shape. Both the designs are checked for aerodynamic (Ansys CFX). Finally comparison of both design shows 27.79% of drag reduction.
