A numerical investigation of viscous, incompressible flow past an axisymmetric body with and without spin
Abstract
This study deals with a preliminary investigation of the effects of spin on the axisymmetric flow past a body of revolution. The study has its genesis larger problem of Magnus forces on spinning bodies at angle of attack. However, the fundamental behavior that arises when a spinning body is placed in a uniform stream is still not well understood; therefore, the problem of axisymmetric flow with spin was undertaken. The body consists of a 3caliber cantogive blunted by a spherical nosecap, a 2caliber cylindrical section, and a 1caliber boattail. Numerical solutions of the compressible laminar NavierStokes equations are obtained using a modified version of the implicitexplicit method developed by MacCormack in 1981. The benchmark problem is the nonspinning body in uniform flow at a Reynolds number of 1.14. The results show that the modified method performs well and allows time steps that are in order of magnitude greater than those permitted by explicit stability criteria.
