Abstract: When the pure electric bus is driving at high speed, the aerodynamic drag increases sharply and brings the problem of continuous mileage anxiety.The authors study aerodynamic characteristics of a pure electric bus through the CFD simulation and wind tunnel testing, and explore the influence law of partial peripheral modelling on aerodynamic drag, in order to build drag reduction scheme of the peripheral modelling of the pure electric bus.
Key words: pure electric; aerodynamic drag; wind tunnel test; CFD simulation
