RISNavier–Stokes Analysis of Turbine Blade Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Comparisons with experimental heat transfer and surface pressures were made for seven turbine vane and blade geometries using a quasi-three-dimensional thin-layer Navier–Stokes analysis. Comparisons ...
Prediction of Surface Roughness and Incidence Effects on Turbine Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The use of a Navier–Stokes analysis to predict the change in turbine efficiency resulting from changes in blade surface roughness or incidence flow angles is discussed. The results of a midspan ...
Heat Transfer Predictions for Two Turbine Nozzle Geometries at High Reynolds and Mach Numbers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Predictions of turbine vane and endwall heat transfer and pressure distributions are compared with experimental measurements for two vane geometries. The differences in geometries were due to ...
Simplified Approach to Predicting Rough Surface Transition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbine vane heat transfer predictions are given for smooth and rough vanes where the experimental data show transition moving forward on the vane as the surface roughness physical height ...
Experimental Determination of Stator Endwall Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Local Stanton numbers were experimentally determined for the endwall surface of a turbine vane passage. A six-vane linear cascade having vanes with an axial chord of 13.81 cm was used. Results ...
Grid Orthogonality Effects on Predicted Turbine Midspan Heat Transfer and Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of five different C-type grid geometries on the predicted heat transfer and aerodynamic performance of a turbine stator is examined. Predictions were obtained using two flow analysis ...
Mach Number Effects on Turbine Blade Transition Length Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of a Mach number correction on a model for predicting the length of transition was investigated. The transition length decreases as the turbulent spot production rate increases. Many ...
Endwall Heat Transfer Measurements in a Transonic Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbine blade endwall heat transfer measurements are presented for a range of Reynolds and Mach numbers. Data were obtained for Reynolds numbers based on inlet conditions of 0.5 and 1.0 × ...
Infrared Low-Temperature Turbine Vane Rough Surface Heat Transfer Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbine vane heat transfer distributions obtained using an infrared camera technique are described. Infrared thermography was used because noncontact surface temperature measurements were desired. ...
The Transport of Vortices Through a Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experiment was conducted to determine how incident vortices created by upstream blade rows interacted with a downstream turbine cascade. Specifically, the kinematics of the vortex transport ...
