WAKE DISTURBANCE APPARATUS FOR REDUCING DRAG TO BE GENERATED IN STUMPY REAR SIDE OF OBJECT AND WAKE DISTURBANCE METHOD

摘要

PURPOSE: A wake agitator and a wake agitation method are provided to reduce the fuel cost of a carrier by reducing the drag generated from the carrier whose a rear side is stumpy and to maximize energy efficiency by greatly decreasing the drag without an extra input of the energy. CONSTITUTION: A disturbance apparatus(10) is protruded from a rear corner of an object(1). Many disturbance apparatuses are arranged in a wake agitator to recover the rear pressure by reducing the intensity of a wake to be generated from the rear side of the object. Thereby, the fuel cost of a carrier is reduced. Moreover, the energy efficiency is maximized by reducing the wake without an additional energy input.
