Magnetohydrodynamic Control of Hypersonic Separation Flows

International Journal of Aerospace Engineering, 2021
Magnetohydrodynamic (MHD) control of hypersonic laminar separation flows is investigated in this paper. A series of numerical simulations over various geometry configurations, namely, a compression corner and a double wedge ramp hypersonic inlet, have ...

Simulations of Hypersonic Boundary-Layer Transition over a Flat Plate with the Spalart-Allmaras One-Equation BCM Transitional Model

Mathematics, 2022
Transitional flow has a significant impact on vehicles operating at supersonic and hypersonic speeds. An economic way to simulate this problem is to use computational fluid dynamics (CFD) codes.

MSAT: Matrix stability analysis tool for shock-capturing schemes

SoftwareX, 2023
The simulation of supersonic or hypersonic flows often suffers from numerical shock instabilities if the flow field contains strong shocks, limiting the further application of shock-capturing schemes.

Multiple temperature model of nonlinear coupled constitutive relations for hypersonic diatomic gas flows

AIP Advances, 2020
The rotational energy of diatomic gases would be activated by the process of intermolecular collisions in high-temperature hypersonic flows. In this paper, a multi-temperature nonlinear coupled constitutive model has been proposed for simulating the ...

Black-box optimization methods for hypersonic flow problems [PDF]

International Journal of Fluid Engineering
This review examines the application of black-box optimization methods to hypersonic flow problems, with a particular emphasis on scenarios where computational fluid dynamics (CFD) simulations function as opaque, nontransparent models.

Review on Oblique Transition

气体物理, 2023
Oblique transition is a transition scenario initiated by a pair of oblique waves with equal but opposite angles. It widely exists in boundary layer flow (over flat plate, cone at zero angle of attack, two-dimensional curved plate etc.), compression ...
