An impulsively started turbulent flow of Mach 0.96 past a projectile model at 60-degree of incidence is considered for investigating the impact of turbulence upon the complex vortical flow physics and phenomena. The unsteady compressible flow problem is assumed to be governed by the Reynolds-averaged thin-layer Navier-Stokes equations for ideal gases and the two turbulence models implemented are the Baldwin-Lomax model and the modified Baldwin-Lomax model. The implication of the two turbulence models has been investigated and quantitative effects of the strong diffusive process of the Baldwin-Lomax model upon the fundamentals and structure of the vortical flow have been numerically obtained and discussed.
