Simulations of Hypersonic Flow past a Re-entry Capsule Using Dsmc Method
DSMC simulation of re-entry of an object with shape and size close to that of ISRO’s Space Recovery Experiment (SRE) capsule has been analysed using the open-source tool dsmcFoam for three altitude conditions, viz. 85 km, 100 km and 115 km, and for three angles of attack, viz. 0, 20&40. The hypersonic free stream velocity of 8000 m/s and boundary surface temperature of 300 K have been used for ...
متن کاملLaminar 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...
متن کاملHypersonic 3-D Blunt Body Equilibrium Air Flow Using High Order WENO Schemes II
We present simulations of Mach 12, 3D, hypersonic turbulent flows of air around blunt bodies with applied magnetic fields of various strengths. We use the Baldwin-Lomax turbulence model. The air is heated by a shock that can change its thermodynamic properties. We treat the air as a real gas in thermodynamic equilibrium. Due to the high temperature the thermodynamic properties of the air are af...
متن کاملAnalytic Solution for Hypersonic Flow Past a Slender Elliptic Cone Using Second-Order Perturbation Approximations
An approximate analytical solution is obtained for hypersonic flow past a slender elliptic cone using second-order perturbation techniques in spherical coordinate systems. The analysis is based on perturbations of hypersonic flow past a circular cone aligned with the free stream, the perturbations stemming from the small cross-section eccentricity. By means of hypersonic approximations for the ...
