Solution of threedimensional afterbody flow using reduced NavierStokes equations
Abstract
The flow over afterbody geometries was investigated using the reduced NavierStokes (RNS) approximation. Both pressure velocity fluxsplit and composites velocity primitive variable formulations were considered. Pressure or pseudopotential relaxation procedures are combined with sparse matrix or coupled strongly implicit algorithms to form a threedimensional solver for general nonorthogonal coordinates. Threedimensional subsonic and transonic viscous/inviscid interacting flows were evaluated. Solutions with and without regions of recirculation were obtained.
