【Abstract】 A numerical technique was developed for solving turbulent flows, employing k-e turbulent model, Beam-Warming implicit finite-difference instationary algorithm and Thompson boundary-conforming curvilineal coordinate systems. The BML Probability Density Function, model for reacting flows was used and an equation of the progress variable c was modified to-character the compustion progress of great Damkholer numbers. Numerical results were presented for both no reacting flows and small thermal expanding rate reacting flows.更多还原
