粘性

This paper studies numerically the influence of the tip clearance on the three-dimensional viscous flowfield and performance of the NASA Low-Speed Centrifugal Compressor impeller with a vaneless diffuser. A three-dimensional viscous code developed by the authors is applied with several acceleration methods: local time-step, multigrid and residual smoothing.

Considering the characters of the viscoidal turbulent flow over high-speed train,the computing model of the outer fiow field for high-speed train has beenestablished based on the incompressible fluid Navier-StOkes epuation and theturbulent model of ke two equations. The equation set of the flow field problemvia finite element methods has been set up.
