Abstract

Reducing energy consumption caused by automobile fuel is an important issue in new energy and energy saving research. Vehicle wind power generation technology can decrease the vehicle non-natural wind energy waste and achieve energy saving and environmentally friendly vehicles. The ducted flow field and pressure field were simulated by the finite element analysis modelling ANSYS to study the influence of the opening tuyere on the vehicles forepart on the energy saving with the drag coefficient as research index. The results showed that the drag decreased during driving with the windward area decreasing and the more uncorking coefficient (Cd) the less drag coefficient. What’s more, drag coefficient decreased by 15% when the ratio of the pipeline diameter and vehicle front-end height (d/h) was more than 0.6. The drag coefficient decreased linearly with the increase of the uncorking coefficient approached a limit value when Cd was more than 0.6 in the vehicle dynamic system of wind and electricity.
