Pulsed Suction Control in a Highly Loaded Compressor Cascade With Low Suction Flowrates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of pulsed suction (PS) on flow separation and aerodynamic performance in a highly loaded compressor cascade is experimentally studied herein. The excitation frequency is investigated as it determines the ...
Aerodynamic Performance and Leakage Flow in Turbine Cascades With Sweeping Jet Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, unsteady flow-control technology has been considered as more promising for reducing secondary flow loss in turbines. Sweeping jet actuators (SJAs), in particular, have steadily been used in turbomachinery ...
Effects of Double-Side Labyrinth Seals on Aerodynamic Performance in a Transonic Shrouded Turbine Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Labyrinth seals on both rotor casing and blade tip as an effective method to control the leakage flowrate of the shroud and improve aerodynamic performances in a transonic turbine stage are investigated in this study. ...
Experimental Investigation for Flow Regime Identification Using Probability Density Function of Void Fraction Signals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, upward air–water two-phase flow tests were carried out in a 3 cm diameter pipe under atmospheric pressure, and over 3000 data points were collected from a wide range of superficial gas and liquid velocities ...
Investigation on Variations of Void Fraction in a Subcooled Boiling Channel Under Vertical Forced Excitations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental tests were carried out to investigate the vertically forced excitation effects on the subcooled boiling flow. The heated circular channel with an inner diameter of 11.9 mm was operated with various heat fluxes ...
