Theoretical Prediction of the Hypersonic Boundary-Layer Over a Row of Microcavities
Abstract
This report results from a contract tasking University of Manchester as follows: The key deliverable will be the ability to provide an improved integral condition for calculations in the main body of the flow. Given the plethora of parameters (M, Re, m, d, d/D, d/s), only a small subset of parameter space will be investigated within the available year; however a theoretical approach provides a fast means to investigate certain parameter regimes. Particular attention will be focused on the choice of (boundary) conditions to be imposed inside the cavity. Various asymptotic limits to the problem will be considered analytically, where appropriate, including the limit of very narrow and also very deep cavities. The possibility of modeling the cavity flow as incompressible will be thoroughly investigated. Also, the sensitivity of some of the underlying assumptions will be investigated. Once the micro' detail of the pressure field has been determined (through analytic and/or numerical means), a study will be undertaken to determine the best/most appropriate manner in which to construct a surface integral condition for use within the outer flow calculations. Progress of the proposed work will be monitored by means of one intermediate and one final report.
