RISUnsteady Loss Mechanisms in Low-Pressure Turbines With Diverging End-Walls Studied Via High-Fidelity Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High-fidelity simulations are used to conduct controlled numerical experiments to investigate the effect of periodically incoming wakes on profile and three-dimensional loss mechanisms. The present work considers the ...
Numerical Design of Experiments for Repeating Low-Pressure Turbine Stages Part II: Effect of Reynolds Number on Different Blade Geometries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The complex transitional and turbulent nature of unsteady flows seen in low-pressure turbines (LPTs) often demands high-order methods such as large eddy simulations (LES) for accurate predictions of turbine ...
