    Abstract
  • The aerodynamical drag of a automobile directly influences its fuel comsumption. For a notchback automobile, its aerodynamical drag relateded with the rear shape amounts to nearly 50 percent of the total aerodynamical drag. Therefore, it is important to make the wake structure clear for designing automobile with good aerodynamic characteristics. The wake structure of notchback automobile and the influence of the rear shape on the structure were analyzed. The result is quite striking for designing new type notchback automobile with good aerodynamic characteristics.
