Turbulent flow over a rough backward-facing step
A journal file contains a sequence of TUI (Fluent) or CCL objects/commands (CFX), arranged as they would be typed interactively into the program or entered through the GUI.... The spanwise invariant flow over a swept, backward-facing step of height H at Re H =C 0 H/?=5000 with turbulent upstream conditions has been studied for sweep angles up

Note These values will allow... flow behind a backward-facing step with a curved nose shape. The laser Doppler anemometry was used as measurement technique. The Reynolds number, Re, based on the step height, h, and the maximum velocity U0max of the velocity distribution at the inlet, was 84000. A Fluent simulation of the flow for the same geometrical and flow conditions as the experimental ones was performed. The resulted

A supersonic flow over an axisymmetric backward facing step model with and without a hydrogen jet was investigated experimentally and numerically. The hypersonic flow of Mach 3.94 was produced by the free-piston wind tunnel of University of Southern Queensland (TUSQ) and the hydrogen supply system was designed to maintain a steady injected fuel
