The Influence of Trailing Edge Ejection on the Base Pressure in Transonic Turbine Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper summarizes the results of base pressure studies on transonic turbine blades in the presence of an ejection of coolant flow from a slot in the trailing edge. The first part of the ...
Recent Progress in the Understanding of Basic Aspects of Secondary Flows in Turbine Blade Passages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper is an attempt to summarize the results of experimental secondary flow research over the past decade in order to give a full picture of our present knowledge and uncertainties ...
Assessment of the Cold-Wire Resistance Thermometer for High-Speed Turbomachinery Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper first describes the fundamentals of cold-wire resistance thermometry. The transfer functions with and without wire-prong heat conduction effects are discussed and a new method for the ...
The Influence of Boundary Layer State on Vortex Shedding From Flat Plates and Turbine Cascades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper aims at a better understanding of the reasons for the wide range of Strouhal numbers observed on turbine blades. The investigation is restricted to the subsonic domain. First, flat ...
The Effect of Vortex Shedding on the Unsteady Pressure Distribution Around the Trailing Edge of a Turbine Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The wakes behind turbine blade trailing edges are characterized by large-scale periodic vortex patterns known as the von Karman vortex street. The failure of steady-state Navier–Stokes calculations ...
Experimental Study of the Three-Dimensional Flow Field in a Turbine Stator Preceded by a Full Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper describes the experimental investigation of the three-dimensional flow field through a low aspect ratio, high turning turbine stator preceded by a full stage. This configuration simulates ...
Influence of Mach Number and End Wall Cooling on Secondary Flows in a Straight Nozzle Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the results of an experimental study of the effect of Mach number and end wall cooling on the secondary flow in a straight nozzle cascade with an aspect ratio of h/c ...
Aerothermodynamics of Low Pressure Steam Turbines and Condensers
Publisher: The American Society of Mechanical Engineers (ASME)
