Experimental, analytical, and computational methods applied to hypersonic compression ramp flows

摘要: Experimental data on fully laminar and transitional shock-wave/boundary-layer interactions in two-dimensional compression corners are provided used for the validation of two full Navier-Stokes solvers, as well checking capabilities limitations simple analytical prediction methods. Viscous pressure interaction, free inviscid oblique shock theory found to predict levels flat plate upstream within separated region, downstream respectively. The reference temperature is perform attached flow regimes both interaction region provide basis a universal peak heating correlation law. Full computations necessary, however, extent associated influence distribution (control effectiveness) detailed heat transfer distribution. To achieve this, very fine gridding coupled with use strict convergence criteria (based evolution location separation point rather than standard density residuals) shown be necessary. It finally that, although sophisticated turbulence models need further developed before characteristics turbulent may predicted, (where transition typically occurs neighborhood reattachment) adequately handled by algebraic "switched on" just reattachment.
