RISA Simplified Model Predicting the Kelvin–Helmholtz Instability Frequency for Laminar Separated Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A semiempirical model for the estimation of the Kelvin–Helmholtz (KH) instability frequency, in the case of short laminar separation bubbles over airfoils, has been developed. To this end, the Thwaites's pressure gradient ...
Off Design Performance of a Highly Loaded Low Pressure Turbine Cascade Under Steady and Unsteady Incoming Flow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The offdesign performance of a highly loaded low pressure (LP) turbine cascade has been experimentally investigated, at the Aerodynamics and Turbomachinery Laboratory of Genova University, under steady and unsteady incoming ...
Noise Source Identification for the Unsteady Low-Pressure Turbine Flow Fields
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The article presents a data processing methodology to identify the noise sources in low-pressure turbine (LPT) stages and their relative importance. Scale adaptive simulation (SAS) has been carried out on a geometry ...
