A numerical and experimental study was carried out for validation of a previously proposed design criterion for a cross-flow turbine and a newsemi-empirical formula linking inlet velocity to inlet pressure. An experimental test stand was designed to conduct a series of experiments and tomeasure the efficiency of the turbine designed based on the proposed criterion. The experimental efficiency was compared to that from numericalsimulations performed using a RANS model with a shear stress transport (SST) turbulence closure. The proposed semi-empirical velocity formulawas also validated against the numerical solutions for cross-flow turbines with different geometries and boundary conditions. The results confirmedthe previous hydrodynamic analysis and thus can be employed in the design of the cross-flow turbines as well as for reducing the number ofsimulations needed to optimize the turbine geometry.
