Research on aerodynamic characteristics of van out from road tunnel under crosswind
A mesh updating method is adopted which based on dynamic layering technique in this paper.The aerodynamic characteristics of vehicles out from road tunnel under crosswind and the causation between the flow phenomenon and the results of mechanical has been studied by setting four pairs of running speed and any running speed corresponding four pairs of wind speed to analyse the aerodynamic characteristics of a van out from road tunnel under crosswind The aerodynamic drag coefficient of the van decreases when running out from the tunnel, the drag coefficient will increase when the wind speed grows.The aerodynamic characteristics of the van seriously fluctuates near the tunnels exit and fluctuation became more obvious when the wind speed increased.The flow field around the van become more complex and effect the safety of driving.
