Computational Study on the Effect of Afd-Body Attachment on Base Drag Using Locked Vortex Method

Abstract

Minimization of drag has always been a concern to achieve high efficiency and performance. Drag reduction techniques can be used to minimize vortex shedding and make. This method can be used for building launch vehicles and missiles. Vortex shedding can be observed when there for over blufſ body, which creates drag. Design modification like the attachment of splitter plates to the base of the body helps to trap the vertices and suppress vortex shedding. It also helps in recovering the pressure at the base of the body. This can be considered as the most effective passive control technique. The paper mainly focuses about the computational study on the effect of aft-body attachment on base drag using locked vortex flow management technique, which proves to be an efficient method in reducing drag.
