Fundamentals of Hypersonic Flow - Aerothermodynamics
To aid in understanding the different topics discussed in the current Lecture Series and to provide background material for interested participants who may not have specialized training in this field, a brief summary of the fundamental attributes of hypersonic flows is given. Many of the topics that are introduced in this section will be elaborated further in contributions related to specific s...
متن کاملPredicting continuum breakdown in hypersonic viscous flows
This paper presents a study of the breakdown of the Navier–Stokes equations in hypersonic viscous flows over a sharp cone tip and a hollow cylinder/flare geometry. Investigations are performed through detailed comparisons of the numerical results obtained with continuum and particle techniques. The objective of the study is to predict conditions under which the continuum approach may be expecte...

متن کاملUncertainty Assessment of Hypersonic Aerothermodynamics Prediction Capability
The present paper provides the background of a focused effort to assess uncertainties in predictions of heat flux and pressure in hypersonic flight (airbreathing or atmospheric entry) using state-of-theart aerothermodynamics codes. The assessment is performed for four mission relevant problems: (1) shock turbulent boundary layer interaction on a compression corner, (2) shock turbulent boundary ...
متن کاملSimulation Techniques in Hypersonic Low-density Aerothermodynamics
Hypersonic rarefied flows near a wedge, disk, plate, and sphere were studied under the conditions of wind-tunnel experiments [1-8] and hypersonic flights. The direct simulation MonteCarlo (DSMC) method [9] is used to study the influence of similarity parameters on aerodynamic coefficients in He, Ar, N2, and CO2. It is found that, for conditions approaching the hypersonic stabilization limit, th...
