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 ...

Experiments have been conducted on a swept wing model in low-turbulence wind tunnel at chord Reynolds number of $2.17 \times 10^{6}$ to investigate the unsteady interaction forward-facing step (FFS) with incoming stationary crossflow (CF) vortices. The impact varying FFS height development and growth primary secondary CF disturbances ensuing laminar–turbulent transition is quantified through de...
