Turbomachinery blade profile optimization method based on through-flow calculation

The invention discloses a turbomachinery blade profile optimization method based on through-flow calculation. The turbomachinery blade profile optimization method comprises the following specific steps: importing a geometric structure, setting through-flow calculation, meshing and calculating through-flow, and optimally setting a blade profile. The method is based on a TurboTides platform one-dimensional centerline module and a geometric structure module, and the one-dimensional centerline module not only provides a geometric structure for the geometric module, but also provides a working condition working medium, a loss coefficient and a blocking coefficient for through-flow calculation; geometric modeling in the geometric module adopts parametric modeling, a geometric curve provides a large number of control points, and multi-angle optimization is provided for blade profile optimization; the blade load is calculated based on the through-flow result, the speed is high, and the calculation precision is high;
