Analysis of Three-Dimensional Viscous Internal Flows.
Abstract
This report describes the technical progress achieved in research sponsored by the Air Force Office of Scientific Research during the period between March 1981 and February 1982. Three areas of research were pursued; two of these consist of analysis of laminar and turbulent duct flows, and study of laminar and turbulent separated flows. Both of these studies were aimed at acquiring a better understanding of isolated physical phenomena significant to turbomachinery applications via the use of appropriate model problems. The third area of research pursued consisted of the analysis of numerical methods with the goal of improving the efficiency and accuracy of the various methods developed and implemented. In the first area of research, fine-grid asymptotic solutions were obtained for laminar flow through curved ducts of simple cross sections; also marching solutions have been obtained for further flow in the entrance region of curved ducts of simple cross sections. The subject of streamwise separation is examined using the laminar flow through a constructed asymmetric channel and the laminar and turbulent flows past a thick blunt plate as the model problems. In the third category, high-Re very fine-grid solutions have been provided for the shear-driven cavity problem using a multi-grid strongly implicit method.
