Superposition of Overall Cooling Effectiveness on a Turbine Blade Leading Edge
Volume 7: Heat Transfer: Combustors; Heat Transfer: Film CoolingAbstract Increasingly harsh turbine environments necessitate the design of more advanced cooling techniques as well as prediction of those cooling schemes’ performance at engine conditions. For several decades, film cooling design has been accelerated through a low-order superposition of adiabatic effectiveness in order to quickly ...

Experimental investigation on the overall cooling effectiveness of t-type impinging-film cooling
Applied Thermal Engineering, 2018Abstract This paper presents an experimental investigation of impinging-film cooling concerning the effects of various factors on overall cooling effectiveness η. The factors include blowing ratio M (0.31 ≤ M ≤ 1.84), non-dimensional jet-to-plate pitch Zn/d (1 ≤ Zn/d ≤ 2), non-dimensional spacing of jet holes Yn/d (1.6 ≤ Yn/d ≤ 2.4) and diameter of ...

Overall cooling effectiveness of effusion cooled annular combustor liner at reacting flow conditions
Applied Thermal Engineering, 2018Abstract A three-sector annular combustor test rig is built to carry out experimental investigation on the liner effusion cooling performance using steady state infrared radiation thermography method at reacting flow conditions. 7 rows of effusion holes in a staggered layout are distributed on both inner and outer liner bended testing plates, where ...

Abstract The overall cooling effectiveness, which represents the distribution of dimensionless temperature on gas turbines surface, is an important parameter for conjugate heat transfer analysis of gas turbines. Generally, it is difficult to measure the overall cooling effectiveness in engine condition.
