Parameterized modeling method of turbine blade cooling <?A3B2 pi6?>inner cavity turbulence rib

<bold> </bold>The turbulence rib is the core structure for enhancing convective cooling in the inner cavity of turbine blades. In order to realize parameterized modeling of complex cooling turbine blade turbulence ribs, a parameterized modeling method for turbulence ribs was proposed. Firstly, the baffle isometric surface and the convex or concave isometric surface were used to trim the rib to ensure the uniform depth of the turbulence ribs. Secondly, a curve recognition algorithm was proposed to establish the relation between the turbulence ribs and the blade inner profile. Then, through the conversion of design parameters to modeling parameters, the precision and efficiency of the turbulence ribs modeling was improved. Finally, UG Open API tool was used to develop a parameterized modeling program for turbulence ribs, and the feasibility of the proposed method was verified.
