Abstract
Provided is a wake disturbing apparatus and method for reducing drag, which can considerably reduce drag caused by a sharp decrease in the pressure behind an object with a blunt trailing edge, such as a vehicle, while the object is traveling at high speed. The wake disturbing apparatus includes a plurality of disrupters, which are arranged at regular intervals along the trailing edge of the object to protrude to a predetermined height so that the vortical strength of the wake occurring around the rear part of the object can be reduced and the pressure at the base surface, which has been decreased due to the wake, can be recovered. Accordingly, it is possible to considerably reduce drag on a vehicle by simply attaching a wake disturbing apparatus to the vehicle without modifying the structure of the vehicle or using additional energy. Thus, it is possible to reduce power consumption of the vehicle and thus maximize the energy consumption efficiency.
