Computation of Non-Isentropic Internal Flows with Variable Density

Abstract

A computational fluid dynamics code named MULTIFLOW-2D has been acquired and is being put into service for the numerical simulation of gas turbine-type combustors. Certain areas of the code were found to be in need of improvement for this application; these are: (1) The grid generation algorithm; (2) The manner of discretisation of the continuity and momentum equations; and (3) The treatment of the inlet boundary conditions. Improvements to these areas were developed and incorporated to the code, and the code functioning in non- reactive flows was tested by means of numerical experiments; verification against physical experiments is planned.
