Stabilisation of second Mack mode in hypersonic boundary layers through spanwise non-uniform surface temperature distribution
L. Boscagli, G. Rigas, O. Marxen +1
The extreme heat fluxes characteristic of hypersonic flows significantly limit the flight envelope of hypersonic vehicles. The role of hydrodynamic instability and the onset of lam…
Control of deterministic breakdown to turbulence of hypersonic boundary layer with spanwise non-uniform surface temperature
L. Boscagli, G. Rigas, P. J. K. Bruce +1
Direct Numerical Simulation (DNS) of a Mach 6 boundary layer over a flat plate is performed to assess the effect of spanwise non-uniform surface temperature on breakdown to turbule…
Hypersonic Boundary Layer Transition and Heat Loading
Ahmad Peyvan, Luis Bravo, Anindya Ghoshal +2
Hypersonic boundary layer transition using high-order methods for direct numerical simulations (DNS) is largely unexplored, although a few references exist in the literature. Exper…
Development of a high-fidelity computational tool for chemically reacting hypersonic flow simulations
Athanasios T. Margaritis, Clément Scherding, Olaf Marxen +2
In this paper, we present a methodology to achieve high-fidelity simulations of chemically reacting hypersonic flows and demonstrate our numerical solver's capabilities on a select…
DeepM&Mnet for hypersonics: Predicting the coupled flow and finite-rate chemistry behind a normal shock using neural-network approximation of operators
Zhiping Mao, Lu Lu, Olaf Marxen +2
In high-speed flow past a normal shock, the fluid temperature rises rapidly triggering downstream chemical dissociation reactions. The chemical changes lead to appreciable changes…
