A Numerical Investigation of Fluid Flow for Disk Pumping Applications

Abstract

This paper describes numerically calculated results obtained for a viscous driven enclosed cavity flow and comparison with the experiments of Daly and Nece (Ref. 4). The sensitive prediction of moment coefficient is chosen for comparison purposes. Some discussion of the impact of k-ε turbulence modeling is also included. A second configuration demonstrating the degree of geometric complexity which can be handled is also presented.

Power Dissipation in Smooth and Honeycomb Labyrinth Seals

“…Chew and Vaughn (1988) compared numerically predicted moment coefficients with the correlation of Daily and Nece and found good agreement over a wide range of Reynolds numbers. Roscoe, et al (1988) modelled the flow in a complex rotating cavity and found good agreement with Daily and Nece for the disk moment coefficient in both laminar and turbulent flow.…”

A CFD Analysis of the Flow in the Impeller Rear Cavity of Aeroengines

“…Ke model has been used by many researchers in predicting the flow in various rotating cavities, e.g. Roscoe et al (1988) and Williams (1989), and it is extended to a multi-scale k-e model by Ko and Rhode (1991) in a rotating cavity flow and thermal calculation. In most of the above work, however, the cavity geometry is rather simple.…”

“…In most of the above work, however, the cavity geometry is rather simple. Only Roscoe et al (1988) did a calculation on a cavity with complicated geometry as is in a turbomachine, but the reported results of this calculation were not extensive.…”

Calculation of Turbulent Flow for an Enclosed Rotating Cone

“…Examples for co-rotating disc systems are given by Chew (1985) and Morse (1988), and for rotor-stator disc systems by Chew and Vaughan (1988), Roscoe et al (1988) and Morse (1989).…”
