Modeling of Laminar-Turbulent Transition for High Freestream Turbulence
Johan Steelant,Erik Dick +1 more
TL;DR: In this paper, the conditionally averaged Navier-Stokes equations are used to simulate transitional skin friction or heat transfer, and a turbulence weighting factor τ is used to describe the diffusion of freestream turbulence into the boundary layer and the intermittent laminar-turbulent flow behavior during transition.
Journal ArticleDOI
Transitional shock-wave/boundary-layer interactions in hypersonic flow
TL;DR: In this article, the authors compared results for transitional interactions on a flat plate at Mach 6 from three different experimental facilities using the same instrumented plate insert, including a Ludwieg tube, an open-jet wind tunnel and a high-enthalpy free-piston-driven reflected shock tunnel (HEG).
Journal ArticleDOI
Towards a unified treatment of fully flashing sprays
TL;DR: In this article, the authors present a systematic study on flashing atomisation, which includes both standards and retrograde fluids, and propose a novel data reduction method in terms of the controlling parameters for (bubble) nucleation.
Journal ArticleDOI
Computational Treatment of Source Terms in Two-Equation Turbulence Models
TL;DR: Different two-equation turbulence models are investigated confirming the generality of the approach and a comparison of both methods shows that the latter is generally applicable and superior to the first, approximate method with respect to convergence speed.
Journal ArticleDOI
Experimental Investigations on Transpiration Cooling for Scramjet Applications Using Different Coolants
TL;DR: In this article, an approach based upon simplified analytical models is presented to analyze the experimental data of throughflow behavior and cooling efficiency and a simplified thermal model is used to analyse the effect of fluid property variations with temperature on pressure loss for different coolants.
