Hybrid Particle–Continuum Simulations of Nonequilibrium Hypersonic Blunt-Body Flowfields

Hypersonic blunt-body flowfields containing a mixture of continuum and nonequilibrium flow are investigated using a modular particle–continuum numerical method. The modular particle–continuum method solves the Navier–Stokes equations in near-equilibrium regions and uses the direct simulation Monte Carlo method in nonequilibriumregions.Hypersonicflowof nitrogen over a two-dimensional cylinder at...

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...

Influence of Cavity Length on Forward-facing Cavity and Opposing Jet Combined Thermal Protection System Cooling Efficiency

A numerical study on the influence of forward-facing cavity length upon forward-facing cavity and opposing jet combined thermal protection system (TPS) cooling efficiency under hypersonic flow is conducted, by means of which the flow field parameters, heat flux distribution along the outer body surface are obtained. The numerical simulation results are validated by experiments and the cooling e...
