Abstract: Additive manufacturing technology provides the possibility of more efficient turbine cooling structures. In this work, a novel structure for turbine air-cooled vane based on fractal structure, named scale cooling structure, ...

Abstract: One of the main causes of damage to gas turbine nozzle guide vanes (NGVs) is creep, which threatens the safety and reliability of gas turbines. Although creep life prediction has been applied to design and maintenance, ...

Abstract: The cooling system design for aircooled turbines is a critical issue in modern gas turbine engineering. Advances in the computational fluid dynamics (CFD) technology and optimization methodology are providing new prospects ...

Abstract: This paper discusses the approach of cooling design optimization of a high-pressure turbine (HPT) endwall with applied 3D conjugate heat transfer (CHT) computational fluid dynamics (CFD). This study involved the optimization ...

Abstract: Film cooling technique is widely used to protect the components from being destroyed by hot mainstream in a modern gas turbine. Combining roundholes is a promising way of improving film cooling effectiveness. A DoE (design ...

Abstract: A tripod cylindrical film hole with asymmetric side holes is studied numerically and experimentally on a flat plate for higher film cooling effectiveness. First, the influences of geometrical parameters are studied and the ...
