Comparison of Eddy Viscosity Models for High Turbulence Nozzle Guide Vane Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we investigate the performance of eddy viscosity turbulence models for high-pressure nozzle guide vane (NGV) flows with engine-realistic turbulence. Using metrics such as integrated kinetic energy (KE) loss ...
Impact of Lean-Burn Combustor Flow on Nozzle Guide Vane Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we investigate the impact of lean-burn-representative swirl and temperature distortion on the aerothermal performance of fully-cooled high-pressure nozzle guide vanes (NGVs) from a modern aero-engine. Experiments ...
Aerodynamic and Thermal Field Development of Cooled Transonic HP NGV
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study we present detailed aerodynamic and thermal field measurements downstream of an annular cascade of fully-cooled nozzle guide vanes (NGVs). The experiments were conducted in the Engine Component Aerothermal ...
Lean-Burn Combustor Simulator for an Engine-Component Test Facility: An Experimental and Computational Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The computational and experimental assessment of a lean-burn low-NOx combustor simulator for an engine component test facility is presented. The Engine Component Aero-Thermal (ECAT) facility is a full-scale engine-parts ...
