Fundamental Study of Three-Dimensional Two Phase Flow in Combustion Systems

Abstract

Extension of a fundamental approach to combustion modelling was continued with development and testing of a flow algorithm suitable for highly swirling flows. The approach was shown to be much superior to current models as indicated by calculated and measured flow fields in a cyclone. Additional turbulence assessments were made by the computation of the performance of a cyclone separator which is a highly swirled device. Good agreement was found between calculated and observed grade efficiency curves. Residence time distribution measurements in a gas turbine using a non-intrusive pulsed mercury tracer were concluded by comparison of measured and calculated functions using the flow trajectory algorithm. Overall these comparisons were found to be good with some discrepancies near the highly swirled region which may be related to the earlier turbulence model which these flow fields used.
