Numerical Simulation of Flow in Linear Cascade With Tip Clearance
Abstract
The evolution of the tip separation vortex, the tip leakage vortex and the passage vortex generated by flow over a low-speed linear compressor cascade with tip clearance was studied by solving the Navier-Stokes equations numerically. The discretization is based on flux-difference splitting, implicit high-resolution scheme. Up to a third-order accurate upwind differencing is achieved through a reconstruction of the solution from it's cell averages. Balwin-Lomax turbulence model with blending function to account for the comer flow was used for the turbulence closure. The formation and the development of the vortices were simulated and were compared with experimental observation.
