Unsteady Losses in Transonic Compressors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A newly developed probe has been used to measure the time-resolved total temperature and pressure in a transonic compressor. The investigation revealed the presence of large fluctuations in the ...
Fan Noise Reduction From a Supersonic Inlet During Simulated Aircraft Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A series of experiments was conducted to investigate the radiation of fan noise from a supersonic inlet during a simulated aircraft approach. A scaled-down model of an axisymmetric, mixed-compression, ...
Experimental Measurements and Modeling of the Effects of Large-Scale Freestream Turbulence on Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of freestream turbulence representative of the flow downstream of a modern gas turbine combustor and first stage vane on turbine blade heat transfer has been measured and analytically ...
Numerical Simulations of Nonreacting Flows for Industrial Gas Turbine Combustor Geometries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study evaluates the application of the computational fluid dynamics (CFD) to calculate the flowfields in industrial combustors. Two-burner test cases, which contain the elemental flow ...
Profile Synthesis and Kinematic Analysis of Pure Rolling Contact Gears
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The kinematic analysis of a type of gearing which allows for power transmission between shafts with pure rolling contact is presented. This proposed gearing is helical and exhibits theoretical ...
The Effects of Freestream Turbulence, Turbulence Length Scale, and Exit Reynolds Number on Turbine Blade Heat Transfer in a Transonic Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper experimentally investigates the effect of high freestream turbulence intensity, turbulence length scale, and exit Reynolds number on the surface heat transfer distribution of a turbine ...
Transonic and Low Supersonic Flow Losses of Two Steam Turbine Blades at Large Incidences
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A linear cascade experiment was conducted to investigate transonic and low supersonic flow losses of two nozzle blades for the steam turbines. In the experiment, flow incidences were changed ...
