...Tianyou Chen; Le Cai; Jun Zeng; Weitao Zhang; Songtao Wang To rapidly and accurately predict turbine rotor blade losses within a wide range of incidences (−50–30 deg), graph neural networks (GNNs) are utilized to predict the aerodynamic parameters of two-dimensional turbine blades based on a small...

...Hangkong Wu; Dingxi Wang; Xiuquan Huang With increasing requirements for high-loading and high-efficiency turbomachines, blades become thinner and thinner and thus design optimizations considering both aerodynamic performances and aeroelastic stability become more and more necessary. In this study...

... squealer tip unsteady VLES heat transfer aerodynamic National Natural Science Foundation of China 10.13039/501100001809 52076165 In modern gas turbines, sufficient tip clearance is required to adjust the relative movement between rotor blades and casing. The over-tip leakage (OTL...

...Xin Yan; Mingliang Ye; Kun He Heat transfer and aerodynamic performance in worn squealer tip gap of a high-pressure gas turbine stage were numerically investigated. Effects of the starting location of wear and wear depth on tip heat transfer coefficient distributions and stage efficiency were...
