Hypersonic Boundary Layer Transition and Heat Loading [PDF]

arXiv
Hypersonic boundary layer transition using high-order methods for direct numerical simulations (DNS) is largely unexplored, although a few references exist in the literature. Experimental data in the hypersonic regime are scarce, while almost all existing hypersonic codes have low-order accuracy, which could lead to erroneous results in long-time ...

An implicit coupling framework for numerical simulations between hypersonic nonequilibrium flows and charring material thermal response in the presence of ablation [PDF]

An implicit coupling framework between hypersonic nonequilibrium flows and material thermal response is proposed for the numerical simulation of ablative thermal protection materials during its flight trajectory. Charring ablative materials, when subjected to aerodynamic heating from hypersonic flows, undergo complex processes such as ablation and ...

Convergence Rate of the Hypersonic Similarity for Two-Dimensional Steady Potential Flows with Large Data [PDF]

arXiv
We establish the optimal convergence rate of the hypersonic similarity for two-dimensional steady potential flows with {\it large data} past over a straight wedge in the $BV\cap L^1$ framework, provided that the total variation of the large data multiplied by $\gamma-1+\frac{a_{\infty}^2}{M_\infty^2}$ is uniformly bounded with respect to the adiabatic ...

Transition mechanisms in hypersonic wind-tunnel nozzles: a methodological approach using global linear stability analysis [PDF]

arXiv
Base-flow computations and stability analyses are performed for a hypersonic wind tunnel nozzle at a Mach number of 6. Isothermal and adiabatic wall boundary conditions are investigated, and moderate stagnation conditions are used to provide representative scenarios to study the transition in quiet hypersonic wind tunnel facilities.

Hypersonic limit of two-dimensional steady compressible Euler flows passing a straight wedge [PDF]

arXiv, 2019
We formulated a problem on hypersonic limit of two-dimensional steady non-isentropic compressible Euler flows passing a straight wedge. It turns out that Mach number of the upcoming uniform supersonic flow increases to infinite may be taken as the adiabatic exponent $\gamma$ of the polytropic gas decreases to $1$.
