Navier-Stokes Simulation of Viscous, Separated, Supersonic Flow Over a Projectile Rotating Band
Abstract
A numerical simulation is made of the separated, turbulent flow over the rotating band of a projectile-like body at Mach numbers 2.5, 3.0, and 3.5. The simulation is made by -solving the thin-layer, compressible, mass-averaged, Navier-stokes equations using an implicit numerical procedure. Numerical solutions are generated on a body-conforming computational grid which is constructed by adapting the boundary conditions of a grid generation scheme which solves the two-dimensional Poisson equations. The computed surface pressure distributions are compared to existing supersonic wind tunnel measurements. An evaluation is made of the accuracy and suitability of the numerical approach, and recommendations are made for the direction of future investigation.
