Abstract : Numerical and laboratory experiments for the incompressible viscous laminar flow over the two-dimensional simple back-step, blunt base, and 45 deg symmetric V-shaped cavity are presented. An explicit time-dependent finite difference scheme was used to obtain the numerical solution of the modelled flow field. A vorticity-stream function scheme, possessing conservative and transportive properties and utilizing upwind differencing for advection terms, yielded stable solutions for Reynolds numbers ranging from 0.1 to 1500. Experimental data obtained from hydrodynamic tow tank tests were compared with numerical results. Good qualitative and quantitative correlation was found. (Author)
