  • Thermal analysis method for ceramic matrix composite (CMC) turbine vane considering micro-woven structure and change of direction of fiber bundles
    Patent number: 12769900
    Abstract: A thermal analysis method for a ceramic matrix composite (CMC) turbine vane considering a micro-woven structure and a change of direction of fiber bundles: obtaining geometric characteristics of the fiber bundles of the internal woven structure of the CMC; establishing a micro-model of warp yarns and weft yarns of the woven structure and a CMC matrix; constructing a woven structural CMC turbine vane model with a micro-structure periodic width in a vane height direction; assigning an anisotropic thermal conductivity matrix varying with a vane profile; performing meshing; performing finite element calculation of a temperature field; and obtaining calculation results of the temperature field of the woven structural CMC turbine vane model, comparing the calculation results with calculation results based on a homogenization thermal analysis method for an equivalent thermal conductivity for analysis, and extracting and analyzing fluctuation characteristics of the temperature field of the woven structural CMC turbin
