RISTotal-Coverage Discrete Hole Wall Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present study investigates heat/mass transfer for flow through perforated plates for application to combustor wall and turbine blade film cooling. The experiments are conducted for hole ...
Heat (Mass) Transfer and Film Cooling Effectiveness With Injection Through Discrete Holes: Part I—Within Holes and on the Back Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A jet stream entering a crossflow is investigated for injection through a single hole and an array of holes for blowing rates of 0.2 to 2.2. The naphthalene sublimation technique has been ...
Heat (Mass) Transfer and Film Cooling Effectiveness With Injection Through Discrete Holes: Part II—On the Exposed Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The heat (mass) transfer coefficient and the film cooling effectiveness are obtained from separate tests using pure air and naphthalene-saturated vapor injected through circular holes into a ...
Effect of Plenum Crossflow on Heat (Mass) Transfer Near and Within the Entrance of Film Cooling Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Convective heat/mass transfer near and within the entrance region of film cooling holes supplied with air from an internal duct (plenum) behind the cooling holes has been measured using a ...
Local Heat/Mass Transfer Measurements in a Rectangular Duct With Discrete Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of arrangement and length of discrete ribs on heat/mass transfer and friction loss is investigated. Mass transfer experiments are conducted to obtain the detailed local heat/mass ...
