Numerical solutions of the Navier-Stokes equations for laminar flow around and beyond the trailing edge of a flat plate at a Reynolds number of 105 are presented. The size of the computational domain has been varied over a wide range to show that previous calculations of this type have employed domains which were too small to obtain a domain-independent solution. The present large-domain solutions are compared with those obtained with the triple-deck and interactive boundary-layer theories. Satisfactory agreement is found in regions of validity of these theories. However, the present results are more complete insofar as they extend well into the asymptotic wake. © 1987 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
