Prediction of Transitional Heat Transfer Characteristics of Wake-Affected Boundary Layers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The presence of wake-passing in the gas turbine environment significantly modifies the heat transfer characteristics on the downstream blade surface by causing wake-induced transition. In this ...
Calculated Design Data for the Multiple-Disk Pump Using Incompressible Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Earlier analyses of the laminar radically outward flow of Newtonian incompressible fluid between parallel corotating disks have been used to calculate the performance of multiple-disk pumps using ...
Axial Pressure Distribution in the Entrance Region of Packed Beds of Spheres
Publisher: The American Society of Mechanical Engineers (ASME)
Full-Coverage Film Cooling—Part I: Comparison of Heat Transfer Data for Three Injection Angles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wind tunnel experiments were carried out at Stanford between 1971 and 1977 to study the heat transfer characteristics of full-coverage film cooled surfaces with three geometries: normal-, 30 deg ...
Hydrodynamic Measurements of Jets in Crossflow for Gas Turbine Film Cooling Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the results of a detailed hydrodynamic study of a row of inclined jets issuing into a crossflow. Laser-Doppler anemometry was used to measure the vertical and streamwise ...
Effects of Density Ratio on the Hydrodynamics of Film Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the results of a detailed hydrodynamic study of a row of inclined jets issuing into a crossflow with a density ratio of injectant to free stream of 2. Laser-Doppler ...
Film-Cooling Effectiveness Downstream of a Single Row of Holes With Variable Density Ratio
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Film-cooling effectiveness was studied using a row of inclined holes that injected cryogenically cooled air across a flat, adiabatic test plate. The density ratio of the coolant to mainstream ...
Gas Turbine Film Cooling: Flowfield Due to a Second Row of Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flowfield measurements with relevance to gas turbine film cooling were carried out behind a second row of holes located 40 hole diameters downstream of a first row and staggered with respect ...
Full-Coverage Film Cooling—Part II: Heat Transfer Data and Numerical Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental research into heat transfer from full-coverage film-cooled surfaces with three injection geometries was described in Part I. This part has two objectives. The first is to present a ...
