Numerical simulation of three-dimensional viscous flow in an isolated axial rotor

摘要

A finite element based Navier-Stokes solver is applied to investigate the three- dimensional viscous flow in a low speed isolated axial rotor with tip clearance at design condition. A higher-order anisotropic eddy viscosity model is used for closure, with wall function treatment able to simulate stationary and moving boundaries. The presented comparisons with experimental data include three- dimensional flow structure behind the rotor as well as the tip leakage flow behaviour developing through the rotor.
