Rychloběžná turbína s nepravidelnou lopatkovou mříží / High Speed Turbine with Non-Uniform Cascade

This doctoral thesis is focused on hydraulic design of axial turbine by CFD and FEM analyses. The results are runners with nonuniform cascades. Nonuniform runners consist of blades with different axial positions, blades with different pitch angles in runner or indifferent blades. Each runner is designed with respect to 3D printing by FDM or SLS technology and hydraulic measuring. The analyses of the excitation frequencies, modal analysis, shape of the turbine operating range, maximal efficiency, output parameters and cavitation properties are emphasized.
