متن کاملStabilization of Hypersonic Boundary Layers by Porous Coatings
A second-mode stability analysis has been performed for a hypersonic boundary layer on a wall covered by a porous coating with equally spaced cylindrical blind microholes. Massive reduction of the second mode ampli cation is found to be due to the disturbance energy absorption by the porous layer. This stabilization effect was demonstrated by experiments recently conducted on a sharp cone in t...
متن کاملDNS of transition in supersonic boundary layers
This paper performs Direct Numerical Simulation of transition induced by blowing and suction in a spatially evolving Mach 2.25 supersonic boundary layer. We use a novel algorithm (Park & Mahesh 2007) capable of solving compressible flow on unstructured grids. Our objective is to evaluate our unstructured capability to simulate supersonic transition. Transition is achieved using controlled perio...
متن کاملNumerical Simulation and Theoretical Analysis of Perturbations in Hypersonic Boundary Layers
T HE progress being made in computational fluid dynamics provides an opportunity for reliable simulations of such complex phenomena as laminar-turbulent transition. The dynamics of flow transition depends on the instability of small perturbations excited by external sources. Computational results provide complete information about the flowfield that would be impossible to measure in real experi...
