RISEffect of Trailing-Edge Ejection on Local Heat (Mass) Transfer in Pin Fin Cooling Channels in Turbine Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments are conducted to study the local heat transfer distribution and pressure drop in a pin fin channel that models the cooling passages in modern gas turbine blades. The detailed ...
Optimization of Air-Cooled Condensers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The essential design parameters for determining the optimum configuration of an air-cooled condenser are identified in this paper. For a power plant operating on a Rankine cycle, expressions for ...
Heat Transfer, Pressure Drop, and Mass Flow Rate in Pin Fin Channels With Long and Short Trailing Edge Ejection Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments have been conducted to study the turbulent heat transfer and friction characteristics in pin fin channels with small trailing edge ejection holes that are commonly found in modern ...
Effect of Rib Angle on Local Heat/Mass Transfer Distribution in a Two-Pass Rib-Roughened Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The heat transfer characteristics of turbulent air flow in a two-pass channel were studied via the naphthalene sublimation technique. The test section, which consisted of two straight, square ...
Turbulent Heat Transfer and Friction in a Square Channel With Discrete Rib Turbulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments study the turbulent heat transfer and friction for fully developed flow of air in a square channel with discrete rib turbulators. The discrete ribs are staggered on two opposite ...
Heat Transfer Characteristics of Turbulent Flow in a Square Channel With Angled Discrete Ribs
Publisher: The American Society of Mechanical Engineers (ASME)
