As a consequence of global warming, new sources of renewable energy are becoming an increasing priority. Archimedes' screw generator allows to transform the potential energy of a fluid at a low-head hydraulic sites into mechanical energy as few generators have been able to do until now. Being a new technology, this thesis tries to provide a numerical research for the study of saidscrew turbineand extract results in the form of efficiency to be able to see the operation of this type of generator.The Navier-Stokes 3D equations are solved with the k-omega SST turbulence model. The geometry of the screw has been provided by an energy consultancy in Regensburg, Germany.
