چکیده
Forewords Computational Fluid Dynamic is becoming a mature discipline in aerospace sciences. It is no longer only an analysis tool but ready to be used in all stages of design as well. The materials here presented review the growth and advances done in the last 10 years for hypersonic flow phenomena in continuum regime. The status of the physical modelling, code development issues such as algorithms, surface and field grid generation and validation data is provided. A number of applications examples for ascent vehicles and atmospheric re-entry vehicles are presented based on lessons learned at the German Aerospace Center, DLR, as well as experiences collected from past European technology programs. The materials here presented highlight future areas of research to enhance accuracy, reliability, efficiency, and robustness on modelling hypersonic flow phenomena.

Analytic 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 ...
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...

Numerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow
Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...
