Turbulent separated and reattaching flow over a backward-facing step was employed as the benchmark-testing configuration,in which be.

The full 2D Navier Stokes equations and VOF technique are adopted to solve numerically problems of the collisions between two interfacial solitary waves and of the transformation of a solitary wave passing over backward step.

Effect of lower-wall slipping on a backward-facing step flow;

Dynamic Hybrid RANS/LES simulation of supersonic flow over back-facing step;

Based on the compressible Navier Stokes equation, subsonic and supersonic turbulent backward facing step flows are computed by using Beam Warming vector splitting form and van Leer flux vector splitting method through Baldwin Lomax algebraic turbulence model and Johnson King non equilibrium algebraic turbulence model.

The hydrogen bubble technique was used to visualize the development and variation of a backward facing step laminar separation flow, which covered basic flow and its unsteady control.

The laser Doppler Velocimeter has been used to measure the shear layer development of laminar separated flow downstream a backward facing step.

The coherent structures of the flows in the recirculate region, reattaching region and tht boundary layer redeveloping region behind a backward facing step were investigated experimentally.
