RISParticle Image Velocimetry Measurements in a High-Speed Low-Reynolds Low-Pressure Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Particle image velocimetry (PIV) measurements in the blade-to-blade (B2B) plane and cascade outlet plane (COP) of a high-speed low-pressure turbine (LPT) cascade were performed at engine-representative outlet Mach number ...
Measurements of Turbulence in Compressible Low-Density Flows at the Inlet of a Transonic Linear Cascade With and Without Unsteady Wakes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present work, hot-wire anemometry was employed for the characterization of the turbulent field at the inlet of a high-speed low-pressure turbine cascade, in terms of turbulence intensity and integral length scales. ...
On the Influence of an Acoustically Optimized Turbine Exit Casing Onto the Unsteady Flow Field Downstream of a Low Pressure Turbine Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern low pressure turbines (LPT) are designed in order to fulfil a various number of requirements such as high endurance, low noise, high efficiency, low weight, and low fuel consumption. Regarding the reduction of the ...
Vane–Probe Interactions in Transonic Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, a numerical investigation of the effect of a miniaturized five-hole probe downstream of a transonic low-pressure turbine vane row is presented. First, a numerical calibration of the probe was performed in ...
