Improved modeling and numerics to solve twodimensional elliptic fluid flow and heat transfer problems
Abstract
A basic, limited scope, fastrunning computer model is presented for the solution of twodimensional, transient, thermallycoupled fluid flow problems. This model is to be the module in the SSC (an LMFBR thermalhydraulic systems code) for predicting complex flow behavior, as occurs in the upper plenum of the looptype design or in the sodium pool of the pooltype design. The nonlinear NavierStokes equations and the twoequation (twovariable) transport model of turbulence are reduced to a set of linear algebraic equations in an implicit finite difference scheme, based on the control volume approach. These equations are solved iteratively in a linebyline procedure using the tridiagonal matrix algorithm. The results of calculational examplers are shown in the computergenerated plots.
