Non-stationary effects in hypersonic nonuniform dusty-gas flow past a blunt body

Hypersonic Blunt Body Computations Including Real Gas Effects

Laminar and Turbulent Aero Heating Predictions over Blunt Body in Hypersonic Flow

In the present work, an engineering method is developed to predict laminar and turbulent heating-rate solutions for blunt reentry spacecraft at hypersonic conditions. The calculation of aerodynamic heating around blunt bodies requires alternative solution of inviscid flow field around the hypersonic bodies. In this paper, the procedure is of an inverse nature, that is, a shock wave is assumed a...

Nonequilibrium Real-gas Effects on Disturbance/bow Shock Interaction in Hypersonic Flow past a Cylinder

The interaction of free-stream disturbances and the bow shock wave in hypersonic ow past a blunt leading edge is an important part of hypersonic boundary layer receptivity to free-stream disturbances. It has been shown that, for a perfect gas, the back and forth interaction and reeection of acoustic waves behind the shock greatly amplify the magnitudes of the disturbance waves. The interaction ...

Computations of Hypersonic Flow of a Diatomic Gas in Rotational Non-Equilibrium past 3D Blunt Bodies Using the Generalized Boltzmann Equation

Direct methods for solving the generalized Boltzmann equation are advanced by simulating flow past threedimensional immersed bodies in diatomic nitrogen in rotational-translational non-equilibrium. The simulations are performed by solving the entire domain with the generalized Boltzmann equation using a solver based upon the conservative discrete ordinates method of Tcheremissine. Coarse and re...
