This paper investigates flow past a backward-facing step (BFS) in duct at Reynolds number $Re = 5080$ based on height, mean inflow velocity and fluid kinematic viscosity. The configuration matches combustion experiment conducted by Pitz Daily 1983. High-resolution fields are obtained OpenFOAM direct numerical simulation, the field analysed Lagrangian approaches. Trajectories of particles areas ...

A numerical study on the influence of forward-facing cavity length upon forward-facing cavity and opposing jet combined thermal protection system (TPS) cooling efficiency under hypersonic flow is conducted, by means of which the flow field parameters, heat flux distribution along the outer body surface are obtained. The numerical simulation results are validated by experiments and the cooling e...
