Qingfeng Cong, Kaiyuan Zhang, Zhigang Li, Jun Li
Journal: Journal of Engineering for Gas Turbines and Power
Publisher: ASME
Article Type: Research-Article
J. Eng. Gas Turbines Power. May 2023, 145(5): 051001.
Paper No: GTP-22-1158

Published Online: December 20, 2022
... performance of rim seal and the cooling characteristics of sealant flow on endwall of a 1.5-stage axial turbine are studied by solving the three-dimensional unsteady Reynolds-averaged Navier–Stokes (URANS) equations via shear stress transfer (SST) turbulence model. Besides, mass transfer analogy is introduced...
