Download or read book Using the Boundary-Layer Equations in Three-Dimensional Viscous Flow Simulation written by William R. Van Dalsem and published by . This book was released on 1986 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple and computationally efficient algorithm for solving the unsteady three dimensional boundary layer equations in a time accurate or relaxation mode is presented. The algorithm is used to compute the separated flow over a 6:1 ellipsoid at angle of attack and the transonic flow over a finite wing with shock induced separation. These results are compared to available experimental data. A method of using the boundary-layer algorithm to accelerate a Navier Stokes computation is also presented. Example computations indicate that a boundary-layer algorithm can be used to improve both the accuracy and efficiency of a Navier Stokes algorithm.
