In this work, the experimental characterization of a Michell-Banki turbine on a laboratory scale is carried out and recommendations are presented for an adequate experimental setup that allows measuring the variables involved in energy generation and adequately characterizing the turbine. The turbine's impeller consisted of 26 blades that were symmetrically arranged between two circular plates. The designed turbine could produce up to 100 W at a water flow rate and head of 0.009 m3/s and 0.6311 m, respectively. The turbine efficiency curve was determined on a hydraulic bench using a torque sensor with encoder. The maximum turbine efficiency was 85%. This technology could be of great help in promoting activities that require electrical energy, such as those related to agriculture, food production, education, and health in areas where access to electricity is limited or non-existent.

The following study proposes the analysis of a Darrieus H-type vertical axis hydrokinetic turbine that can be implemented in regions not interconnected to the Colombian electricity system, especially coastal areas. The objective of the study is to analyze the number of blades in the efficiency of the hydrokinetic turbine, for this, 27 types of rotors are proposed, in which, the number of blades is varied from 2 to 10 for 3 different solidity values. Concluding that from 3 blades the negative torques produced are reduced, increasing the capacity of auto-start, however, when the number of blades increases the total torque generated by the turbine decreases which leads to a decrease in efficiency.
