An efficient computational tool for ramjet combustor research
Conference
·
OSTI ID:5142883
A multigrid based calculation procedure is presented for the efficient solution of the time-averaged equations of a turbulent elliptic reacting flow. The equations are solved on a non-orthogonal curvilinear coordinate system. The physical models currently incorporated are a two equation k-epsilon turbulence model, a four-step chemical kinetics mechanism, and a Lagrangian particle tracking procedure applicable for dilute sprays. Demonstration calculations are presented to illustrate the performance of the calculation procedure for a ramjet dump combustor configuration. 21 refs., 9 figs., 2 tabs.
