Fluid dynamic design of an axial rotor for hydrokinetic riverbed turbine‐improvement introduced by a high lift foil profile

Abstract

The main objective of this paper is to achieve a very high lift rotor to take the maximum advantage of the kinetic energy of a slow velocity water flow, which belongs to a lowland river type. Low speed flux and lack of depth are the main obstacles in hydrokinetic operation. The use of a high lift aerodynamic profile and the gain of the rotor number of blades serve to accomplish the task.
