The paper presents the computational investigations of model Francis turbines (for high kinematic specific speed 95–115. Numerical calculations were carried out for flow systems including two different Francis runners. The computational fluid dynamics (CFD) analyses were performed for accurately mapped geometry of the laboratory test rig with installed model turbine. Commercial software was used for analysis.
