摘要：
Large-eddy simulation (LES) results of the turbulent flow field in a 72. segment of a rotating axial fan are discussed. A newly developed finite-volume flow solver which is based on non-boundary-fitted Cartesian grids is used to solve the three-dimensional flow equations for viscous compressible fluids. Computations are performed for two operating points at a constant Reynolds number of 9.36 x 10(5) based on the outer casing wall diameter. The capability of the method to accurately resolve the main flow phenomena including the unsteady turbulent tip-gap vortices is demonstrated.
