Effect of Aerodynamic Forces over the Bus Body and Design of Conceptual Bus for Enhanced Performance
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2014, Vol 11, Issue 4
Abstract
Buses are preferred as the major mode of mass transportation round the globe. In recent times hike in fuel price is meticulously observed and pertaining to current day’s strict government norms, current buses are on track of being much more inefficient in terms of fuel costs. Aerodynamically efficient and accordingly redesigned bus body may improve their fuel economy. Even fuel used being from natural source, saving it will be a boon for mankind. To achieve better economy and good performance, it is necessary to redesign a vehicle with minimum drag resistance. This study relates three redesigned and retouched model of buses among themselves and their analysis for obtaining better aerodynamic design through ANSYS Fluent 14.5 package. CFD’s aerodynamic simulations can give the detailed idea of the various parameters for all models which assist in redesigning the bus. This work depicts how the modifications could reduce the drag and the lift forces acting on the vehicle. Study includes the effect of variation of different parameters such as floor panel height, diffuser angle as well as modifying the edges for a bus body over the resisting forces. Attached streamline flow as being ideal flow was obtained for a model. CFD analysis for redesigned models shows remarkable results for the reduction in drag values and lift values. Drastic reduction in the pressure at front and wake region was obtained. Redesigning the overall body shape also improves vehicle stability and handling.
