Parametric optimization of flow part of high-speed turbodrill

The article presents the results of research on parametric optimization of the flow part of the hydraulic turbine of a high-speed turbodrill. The developed parametric model was used as an initial model for optimization of the flow part geometry. Correlation studies were performed, which allowed to determine the design parameters that have the greatest influence on the integral energy characteristics of the turbine and were set as input parameters for optimization. Optimization of the flow section using direct methods and a surrogate predictive model was carried out. A significant increase in the efficiency of the turbine flow part was obtained.
