摘要：

The paper reports on the study of flow structure of a reacting propane-air jet, issued from contraction nozzle and impinged on flat metallic surface, by using the particle image velocimetry technique. Flows with different nozzle-to-surface distance H/d were studied. The Reynolds number Re was in the range of 500 divided by 5500, equivalence ratio Phi was varied from 0.8 to 1.4. Velocity field was measured for a conical premixed flame for Re = 1500 and Phi = 0.9. A region with flow recirculation was detected between the flame cone and the impingement surface for the case of H/d = 4. This flow feature may result in a reduced local heat transfer.
