Abstract

This paper presents results of a research hydro turbine in a Venturi tube for given revolutions per minute and velocity of water at the entry of the tube. The results were obtained with commercial software for numerical fluid dynamics. The research was included comparison of power obtained with one and two contra-rotating hydro turbine in a Venturi tube.
The numerical simulations, for two turbines rotating in opposite directions with equal angular velocities, showed that a considerable power drop occurred, whereas the total power is somewhat larger than for the one turbine.

Keywords

Contra-rotating hydro turbine; Numerical fluid dynamics; Venturi tube
