description: The focus of the work is on the calculation of the flow part of the PL20-811 hydro turbine. Geometric parameters and dimensions of the spiral chamber and suction pipe are calculated. To determine the power and efficiency of the hydro turbine, three flow part models of the PL20-811 turbine with different guide vane positions were constructed. The aim of the research project is to develop a solid computational model of the PL20-811 turbine, calculate the power and efficiency of the model, and compare the parameters with the test results. The established flow regime of the working fluid in the turbines flow section is analyzed using CAD software SolidWorks and ANSYS. The following results were obtained: the efficiency of the calculated model was 90.2%, 88.5%, and 89.5% for powers of 12.7 kW, 12.5 kW, and 12.6 kW respectively. Experimental parameters for comparison included 12.9 kW at 90.5% efficiency. The difference in results was approximately 3%. The research project findings can be applied to practical tasks such as selecting the operating mode of the PL20-811 turbine, as well as for scientific research purposes such as exploring turbine operation modes.
