RISReduced-Order Models for Effusion Modeling in Gas Turbine Combustors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Effusion cooling represents the state-of-the-art for liner cooling technology in modern combustion chambers, combining a more uniform film protection of the wall and a significant heat sink effect by forced convection ...
Numerical Investigation on the Effect of Rotation and Holes Arrangement in Cold Bridge-Type Impingement Cooling Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents the results of a numerical analysis performed on a gas turbine leading edge cooling system. The investigation was carried out in order to provide a detailed interpretation of the outcomes of a parallel ...
Numerical and Experimental Analysis of the Tip Leakage Flow in a Squealer Low-Pressure Turbine Blade for Different Operating Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study combines experiments and numerical simulations (3D-Reynolds-averaged Navier–Stokes (RANS)) to achieve a deep understanding of the effects induced by varying key parameters affecting tip leakage flow ...
Optimization of Endwall Ridging for Enhanced Efficiency in Aggressive Turbine Vaned Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study presents a joint experimental and numerical investigation on the impact of endwall ridging on the efficiency of a turbine nozzle guide vane (NGV). Experiments are conducted on a large-scale, low aspect ...
