Abstract
The influence of the initial conditions used when modeling atomized fuel on the accuracy of gas temperature field non-uniformity at the exit of a helicopter gas turbine annular reverse-flow combustor is analyzed. The analysis is based on the numerical solution of the problem of a three-dimensional two-phase flow with combustion. Computations for four models of fuel droplet feed are based on the integration of Reynolds equations for the gas phase and Lagrange equations for the fuel droplets. The influence of the initial conditions on the combustor exit gas temperature field non-uniformity is found to be insignificant. The comparison of the numerical results with the test data showed their better agreement for radial rather than circumferential nonuniformity.
