Formulation, stability and application of a semi-coupled 3-D four-field algorithm

PDF Version Also Available for Download.

Description

A new 3-D four-field algorithm has been developed to predict general two-phase flows. Ensemble averaged transport equations of mass, momentum, energy and turbulence transport are solved for each field (continuous liquid, continuous vapor, disperse liquid, disperse vapor). This four-field structure allows for analysis of adiabatic and boiling systems which contain flow regimes from bubbly through annular. Interfacial mass, momentum, turbulence and heat transfer models provide coupling between phases. A new semi-coupled implicit method is utilized to solve the set of 25 equations which arise in the formulation. In this paper, three important component numerical strategies employed in the method are ... continued below

Description

A new 3-D four-field algorithm has been developed to predict general two-phase flows. Ensemble averaged transport equations of mass, momentum, energy and turbulence transport are solved for each field (continuous liquid, continuous vapor, disperse liquid, disperse vapor). This four-field structure allows for analysis of adiabatic and boiling systems which contain flow regimes from bubbly through annular. Interfacial mass, momentum, turbulence and heat transfer models provide coupling between phases. A new semi-coupled implicit method is utilized to solve the set of 25 equations which arise in the formulation. In this paper, three important component numerical strategies employed in the method are summarized. These include: (1) incorporation of interfacial momentum force terms in the control volume face flux reconstruction, (2) phase coupling at the linear solver level, and in the pressure-velocity coupling itself and (3) a multi-step Jacobi block correction scheme for efficient solution of the pressure-Poisson equation. The necessity/effectiveness of these strategies is demonstrated in applications to realistic engineering flows. Though some heated flow test cases are considered, the particular numerics discussed here are germane to adiabatic flows with and without mass transfer.
