1. Numerical investigation of aerothermodynamic in a reentry vehicle with surface discontinuity-like cavity / Investigação numérica da aerotermodinâmica de veículos na reentrada com imperfeições na superficie do tipo cavidade
In the design of hypersonic vehicles, the knowledge of factors that affects the thermal and aerodynamic loads acting on the vehicle surface becomes imperative. Usually, in the thermal load calculations, the analysis assumes that the vehicle has a smooth surface. However, discontinuities or imperfections are present on the surface of reentry vehicles. In this

2. Gas-surface interaction effect on round leading edge aerothermodynamics
Effects of incomplete surface accommodation in rarefied gas flow have been studied by using the Direct Simulation Monte Carlo (DSMC) method in conjunction with the Cercignani-Lampis-Lord gas surface interaction model. The DSMC calculations examine differences in predictions of aerodynamic forces and heat transfer between full and partial surface accommodatio

3. Simulation of blunt leading edge aerothermodynamics in rarefied hypersonic flow
The steady-state aerodynamic characteristics of a new family of blunted leading edges immersed in a high-speed rarefied air flow are examined by using a Direct Simulation Monte Carlo (DSMC) Method. A very detailed description of the flow properties has been presented separately at the vicinity of the nose and adjacent to the afterbody surface of the leading

4. Effects of compressibility on aerodynamic surface quantities over low-density hypersonic wedge flow
Hypersonic flow past truncated wedges at zero incidence in thermal non-equilibrium is investigated for a range of Mach number from 5 to 12. The simulations were performed by using a Direct Simulation Monte Carlo (DSMC) Method. The study focuses the attention of designers of hypersonic configurations on the fundamental parameter of bluntness, which can have a
