Design and numerical analysis of an efficient H-Darrieus vertical-axis hydrokinetic turbine
Journal of Mechanical Engineering and Sciences, 2019 Hydrokinetic turbines are one of the technological alternatives to generate and supply electricity for rural communities isolated from the national electrical grid with almost zero emission. The Darrieus turbine is one of the options that can be used as

Design of a hydrokinetic turbine [PDF]
WIT Transactions on Ecology and the Environment, 2015 Hydrokinetic turbine power production depends on the interaction between the rotor and water. Therefore, an optimum geometry of the rotor must be designed and constructed to capture the maximum water energy and convert it into a usable energy. The steps involved in the design and numerical simulation of a small horizontal axis hydrokinetic turbine ...
