In the present research work, a device for electrical energy generation from water pipeline has been designed, simulated and tested. To achieve this, a study of the most influential parameters involved in the experiment has been carried out and both, the turbine model and the geometry of the experimental test pipe, have been selected through CFD simulations. Next, Design Of Experiments (DOE) has been used in order to obtain the configuration with a higher energy extraction to running water. Finally, the turbine and the test pipe section have been manufactured by 3D printing and the experimental tests have been carried out with the optimal configuration so as to validate the results obtained in the CFD simulations. To simulate the exchange of energy between the water and the turbine, the CFD XFlow software has been used
