This book was released on 1986 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Implicit, approximately factored, finite difference codes have been developed for solving the Navier-Stokes equations in general body-fitted coordinates. For a protuberance such as the rotating band on artillery shell, sharp geometric variations exist which make it extremely difficult to generate body conforming grids while preserving the sharp corners. Using wrap around grids for such cases introduces geometric errors and may lead to degradation of computational efficiency and accuracy. This report describes the development and application of a computational procedure using flowfield blanking to compute the flow over a rotating band at supersonic speed with no geometric error. Keywords: Supersonic Flow; Navier Stokes; Flowfield Blanking; Rotating Band.
