RISHigh-Fidelity Computational Fluid Dynamics Analysis of In-Serviced Shrouded High-Pressure Turbine Rotor Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In-service deterioration can lead to undesired shape variations on high-pressure turbine rotor blades. This can have a significant impact on efficiency, power generation, and component life. Loss of power production from ...
Aerothermal–Structural Optimization of a High-Pressure Turbine Rotor With Robustness Evaluation to in-Service Deterioration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This article presents a multidisciplinary optimization conducted on the high-pressure turbine rotor of a commercial turbofan engine. The rotor geometry is parametrized using a compact orthogonal design space, and ...
Discussion: “Unsteady RANS Simulations of Wells Turbine Under Transient Flow Conditions” (Hu and Li, ASME J. Offshore Mech. Arct. Eng., 140(1), p. 011901)

A Critical Examination of the Hysteresis in Wells Turbines Using Computational Fluid Dynamics and Lumped Parameter Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hysteretic behavior of oscillating water column (OWC)-installed Wells turbines has been known for decades. The common explanation invokes the presence of unsteady aerodynamics due to the continuously varying incidence ...
