Viscous Flow Analysis of a Submarine with Variation of Angle of Attack and Yaw Angle
유동 방향 변화에 따른 잠수함 주위의 3차원 점성유동 해석과 공기역학적 계수의 변화
Abstract
In this paper, the submarine model, called DARPA SUBOFF model, has been numerically analyzed to investigate the aerodynamic forces variation in terms of angle of attacks and yaw angles. The SUBOFF model is consisted of the three parts : axisymmetric body, fairwater, and four symmetric stern appendages. Three dimensional unsteady incompressible Wavier-Stokes equation was used on curvilinear multi-block grid system. To validate the present code, the SUBOFF tare hull and an ellipsoid at angle of attacks of
