Abstract

In this study, an experimental evaluation of fourgeometric configurations of gravitational vortex turbines was conducted. The configurations result from the combination of two types of inlet channels: a tangential and a spiral, and two types of discharge chambers: a cylindrical and a conical one. The models were fabricated at laboratory scale and tested in a hydraulic test bench under controlled conditions. The configuration combining a spiral inlet channel and a cylindrical discharge chamber exhibited the highest hydraulic efficiency of 60.85%. These tested geometric configurations can be used for distributed generation.
