Abstract:

A three-dimensional computational procedure is presented for calculating the coupled flow and chemistry within rectangular or axisymmetric combustors with a discrete circumferential distribution of injection ports. The compressible time-averaged Navier-Stokes equations are solved with coupled pseudo-kinetic hydrocarbon chemistry including the effects of turbulence, droplet vaporization and burning, and radiation transport. An eddy viscosity turbulence model with an ad hoc specified mixing length distribution is employed at present. The governing equations are solved using the Multidimensional Implicit Nonlinear Time-dependent MINT procedure, which employs a unique linearization technique and a Douglas-Gunn alternating-direction-implicit ADI scheme. Calculations were made for the flow in a rectangular combustion chamber with a discrete distribution of inlet injection ports and the results are compared with the experimental data available for this configuration.
