RISEffects of Cooling Configurations on the Aerothermal Performance of a Turbine Endwall With Jet Impingement and Film Cooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increase of turbine inlet temperature and the application of premixed combustion, turbine components, particularly the turbine endwall, work in a harsh environment and must be effectively cooled to ensure the ...
A Novel Multi-Fidelity Surrogate for Efficient Turbine Design Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To solve the turbine design optimization problems efficiently, surrogate-based optimization algorithms are frequently used. To further reduce the cost of turbine design, the multi-fidelity surrogate (MFS)-based optimization ...
Multi Objective Aerodynamic Optimization Design and Data Mining of a High Pressure Ratio Centrifugal Impeller
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An automated threedimensional multiobjective optimization and data mining method is presented by integrating a selfadaptive multiobjective differential evolution algorithm (SMODE), 3D parameterization method for blade ...
Research on Metamodel Based Global Design Optimization and Data Mining Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The turbomachinery cascades design is a typical high dimensional computationally expensive and black box problem, thus a metamodelbased design optimization and data mining method is proposed and programed in this work, ...
Reliability-Based Design Optimization of Complex Problems With Multiple Design Points via Narrowed Search Region
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The expensive computational cost is always a major concern for reliability-based design optimization (RBDO) of complex problems. The performance of RBDO can be lowered by the inaccuracy of reliability analysis (RA) which ...
