RISFull Coverage Film Cooling: Heat Transfer Coefficients and Film Effectiveness for a Sparse Hole Array at Different Blowing Ratios and Contraction Ratios
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present experimental investigation considers a full coverage film cooling arrangement with different streamwise static pressure gradients. The film cooling holes in adjacent streamwise rows are staggered with respect ...
Full Coverage Film Cooling: Film Effectiveness and Heat Transfer Coefficients for Dense Hole Arrays at Different Hole Angles, Contraction Ratios, and Blowing Ratios
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental results are presented for a fullcoverage film cooling arrangement which simulates a portion of a gas turbine engine, with appropriate streamwise static pressure gradient. The test surface utilizes varying ...
