INVESTIGATION OF SUPERSONIC TRANSPIRATION COOLING THROUGH SINTERED METAL POROUS FLAT PLATES
要約
The flow and heat transfer characteristics of supersonic transpiration cooling through sintered porous flat plates were investigated experimentally and numerically. The experiments were conducted in a Mach 2.8 wind tunnel with air as the main flow and coolant. The porous wall temperatures were measured with an infrared camera and the flow field was observed with a Schlieren imaging system. Influences of coolant blowing ratio and porous matrix thermal conductivity on the cooling efficiency were analyzed, which showed that the surface temperatures were reduced significantly with a small amount of coolant injection rate. Moreover, a higher thermal conductivity of the porous matrix improved the cooling effect and the surface temperature uniformity. The Schlieren images showed that an oblique shock wave induced by the blockage effect of the injected coolant and the shock wave intensity increased with the increasing coolant blowing ratio.
