RISFull-Coverage Film Cooling: Film Effectiveness and Heat Transfer Coefficients for Dense and Sparse Hole Arrays at Different Blowing Ratios
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental results are presented for a full coverage film cooling arrangement which simulates a portion of a gas turbine engine, with appropriate streamwise static pressure gradient and varying ...
Separate Effects of Mach Number and Reynolds Number on Jet Array Impingement Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Limited available data suggest a substantial impact of Mach number on the heat transfer from an array of jets impinging on a surface at fixed Reynolds number. Many jet array heat transfer ...
Influence of Surface Roughness on the Aerodynamic Losses of a Turbine Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of surface roughness on the aerodynamic performance of a turbine vane are investigated for three Mach number distributions, one of which results in transonic flow. Four turbine ...
Effect of Temperature Ratio on Jet Array Impingement Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper consider the effects of temperature ratio on the heat transfer from an array of jets impinging on a flat plate. At a constant Reynolds number of 18,000 and a constant Mach number ...
