| Abstract: | In this paper, numerical simulation is applied to investigate thenear field aerodynamic characteristics of asymmetry spherical forebody of blunt body. The problems are formulated by using the unsteady, compressible Navier Stokes equations. The equations are solved by using NND scheme, the modified Baldwin Lomax algebraic model is used to numerically simulate separated flows around a blunt body, the results are fit well with the experiment data. |
