Transpiration cooling technology for ceramic matrix composite blade:review and prospect
摘要
Abstract
To ensure the normal operation of turbine blades Facing continuously increasing turbine inlet temperatures,the development of more efficient cooling technologies has become particularly urgent.Ceramic matrix composite(CMC)transpiration cooling technology combines the excellent high-temperature resistance of CMC with the efficient heat dissipation potential of transpiration cooling,showing broad application prospects in future thermal protection of turbine blades.However,the strong anisotropy of CMC materials and their complex internal porous structure pose significant challenges for the thermal analysis of the transpiration cooling process,and the underlying flow and heat transfer mechanisms remain unclear.This review summarized recent research progress on the anisotropic thermal conductivity and microporous seepage characteristics of CMC,analyzed key existing problems and challenges in current studies,and offerd suggestions for establishing a comprehensive design framework for CMC turbine blade transpiration cooling structures.关键词
