Mathematical Modelling of an Annular Gas Turbine Combustor

Mathematical model for description of axisymmetric swirled flow with diffusion combustion is based on numerical solution of Reynolds equation with k-W modell of turbulence. The results of numerical and experimental investigations of local and general characteristicse of flow, heat and mass transfer, combustion and NOx formation in annular combustor with opposite swirled air jets are presented. Satisfactory agreement between calculations and experiments is obtained. The dependences of combustor characteristics vs geometric and operational parameters are generalized.Copyright © 1993 by ASME
