• Cascade flow
• Multi block grid structure
• Tip clearance flow

The tip-clearance flow in a cascade was numerically simulated by solving the RANS equations of incompressible fluids. The computational model is based upon the artificial compressibility formulation proposed by Chorin. The Baldwin-Lomax turbulence model is used to enclose the governing equations. Considering the special features of tip-clearance flow, a multi-block grid structure is adopted to facilitate numerical computations. The comparison of the numerical results with the experimental data indicates that the present method is capable of simulating tip-clearance flows with satisfying accuracy.
