Abstract
In this article is present the procedure for the design of all components of a pico-hydro system, is designed a pico hydraulic propeller turbine according to the specific condition of water potential to an estimated site of operation based on a theoretical and technical analysis. For this purpose, the main characteristics of the runner are determined for medium of statistics correlations of different designs of turbine around the world, and defining restrictions for the design such as turbine head, nominal rate flow and power required, from the data mentioned above, the value of all the variables related to the behavior of the fluid in its passage through the impeller is established and from the value of said variables and the geometry established for the impeller, the geometry is determined and the specifications of the other components of the pico-hydro system such as the spiral chamber, the suction tube, the generator and the distributor, for which two types were studied, which are a distributor of axial input of the fluid and another radial input of the fluid with respect to the axis of rotation of the turbine. For the verification of the design and expected results, a modern engineering tool is used, such as computational fluid dynamics (CFD), especially the component (CFX) to predict the flow and performance that the designed system can produce. Finally, a technical-economic analysis is carried out to study the feasibility of implementing this type of systems in a rural area.
The design of the present pico-hydro system and the contribution of computational fluid dynamics CFD, can be a viable alternative to meet the demands of electricity in a rural area that does not have this service by the supply networks responsible for this function.
