RISApplication of Unsteady Computational Fluid Dynamics Methods to Trailing Edge Cutback Film Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The main purpose of this numerical investigation is to overcome the limitations of the steady modeling in predicting the cooling efficiency over the cutback surface in a high pressure turbine nozzle guide vane. Since ...
Stress-Blended Eddy Simulation of Coherent Unsteadiness in Pressure Side Film Cooling Applied to a First Stage Turbine Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Within the framework of scale resolving simulation techniques, this paper considers the application of the stress-blended eddy simulation (SBES) model to pressure side (PS) film cooling in a high-pressure turbine nozzle ...
Improving the Film Cooling of a Rotor Blade Platform
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper shows the results of an experimental activity developed in cooperation between Ansaldo Energia and the Department of Engineering and Applied Science of Bergamo University with the aim of assessing the impact of ...
Assessment of Transition Modeling and Compressibility Effects in a Linear Cascade of Turbine Nozzle Guide Vanes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow field in a linear cascade of highly loaded turbine nozzle guide vanes (NGVs) has been numerically investigated at low and high-subsonic regime, i.e., exit isentropic Mach number of M2is = 0.2 and 0.6, respectively. ...
Simulation of Solarized Combined Cycles: Comparison Between Hybrid Gas Turbine and ISCC Plants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper investigates two different solarized combined cycle layout configurations. In the first scheme, a solarized gas turbine is coupled to a solar tower. Pressurized air at the compressor exit is sent to the ...
