An Experimental Study of Plunging Liquid Jet Induced Air Carryunder and Dispersion

Abstract

This report period has been primarily concerned with the development of a two-fluid Computation Fluid Dynamics (CFD) model for a free two-phase jet. This model has been implemented into PHOENICS and evaluated on a RISC/6000 work station and the CRAY YMP-8 at Stennis Space Center. We first present a state-of- the-art two-fluid model for air/water flows, which consists of the phasic three- dimensional conservation equations of mass and momentum. The associated closure conditions will also be discussed, along with some general constraints, followed by specific constitutive relations for low void fraction bubbly two-phase flows. Finally, the results of the numerical evaluation of a planar plunging liquid jet will be presented.
