Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Mechanical Power Engineering Summary: Mini-hydropower plants play an important role in supplying power to remote areas. This study focuses on studying the cross-flow hydraulic turbine as an outstanding example of mini-hydraulic turbines. The study is performed using CFD analysis to assess the most appropriate design parameters that can improve the cross-flow hydraulic turbine performance. The study started with reviewing the outstanding previous studies and the comparative study of the available data yielded a set of design parameters that are expected to constitute the optimum design parameters for a high-performance cross-flow turbine. From that study, it was found that a newly defined specific speed (named unified specific speed) can be used better to define the geometry of the radial section of the turbine irrespective of rotor width. The comparative study optimum design parameters were tested using a numerical model using ANSYS Fluent 15.0 software. The results showed the maximum efficiency was enhanced from 62.9% to 67.12% when applying the recommended optimum parameters for the numerically investigated turbine
