AN EXPERIMENTAL INVESTIGATION OF ADIABATICEFFECTIVENESS OF INCLINED MULTIHOLE WALL FULL-COVERAGE FILM COOLINGWITH HEAT-MASS TRANSFER ANALOGY METHOD
experimental research was carried on to investigate adiabatic film effectiveness of inclined multi-hole full-coverage film cooling.The hole configurations were regular patterns of staggered discrete circular holes
and holes inclined at an angle of 30 deg to the surface of experimental plate. Spanwise hole-to-hole spacing range is from 60 mm to 90 mm
streamwise row-to-row spacing from 45 mm to 18 mm
and hole diameter from 1.0 to 20 mm.Within the range of blowing ratio from 1.0 to 4.0
the experimental results of the adiabatic film effectiveness distribution for five plates were compared and analyzed.Finally
the optimum number of hole spacing and row spacing as well as the influences ofblowing ratio on the adiabatic film effectiveness were obtained.
