Comparative study of equilibrium and non-equilibrium predictions by different models for a hypersonic cone at high-altitude
Mengyu Wang, Pan Yan, Qin Li +3
Targeting a cone with the half-angle as 10-deg at M = 27 and H = 72 km, simulations were conducted comparatively to analyze the predictions by different equilibrium and non-equilib…
Numerical study of friction reduction and underlying mechanism of air film via parallel and tandem injections on a hypersonic flat plate at high altitude
Xiuzheng Cheng, Mengyu Wang, Qin Li +3
This study uses numerical simulations to analyze a flat-plate with air films generated via parallel and tandem injections under freestream conditions of Ma=15 at an altitude of H=6…
Evolution and sudden change of steady interactions of low enthalpy hypersonic double wedge flows with fore angle
Yihui Weng, Yi Duan, Qin Li +4
The evolution and sudden change of steady interaction structures is numerically studied with the fore wedge angle theta_1 in a low enthalpy hypersonic double wedge configuration. I…
Numerical studies on steady interaction of low enthalpy hypersonic double wedge flows using different gas models
Qin Li, Y Wang, Yihui Weng +5
Numerical investigations and analyses are carried out particularly on the steady interactions of low enthalpy hypersonic 30-55-deg double wedge configuration at conditions similar…
