The turbulence statistics of an unsteady separated ยฏow was experimentally investigated. A backward-facing step ยฏow at Re 3700 was chosen as the test case, where periodic perturbation was introduced from its step edge. A two-dimensional particle imaging velocimeter (PIV) was used in the ยฏow-ยฎeld meas

Laminar forced convection flow of nanofluids over a 2D horizontal backward facing step placed in a duct is numerically investigated using a finite volume method. A 5% volume fraction of nanoparticles is dispersed in a base fluid besides using various types of nanoparticles such as Au, Ag, Al 2 O 3 ,
Particle-laden flows are calculated for a classical laminar backward-facing step problem. The particle tracks are calculated using a recently developed exponential Lagrangian tracking scheme. The behaviour of the particleladen flow is considered for various inlet for Reynolds number, Stokes numbers
The study investigates the entrance effect for ยฏow over a backward-facing step by comparing predictions that set the inlet boundary at various locations upstream of the sudden expansion. Differences are most signiยฎcant in the sudden expansion region. If the geometry has an inlet channel, then shorte
A numerical investigation of laminar flow over a three-dimensional backward-facing step is presented with comparisons with detailed experimental data, available in the literature, serving to validate the numerical results. The continuity constraint method, implemented via a finite element weak state
