The paper is dedicated to the study of aerodynamic effects in small power wind turbine rotors using mathematical models to describe the fluid flow physics and modern methods of numerical simulation in the framework of computational fluid dynamics (CFD). There was argued the geometry of blades' aerodynamic profiles efficient in terms of energy conversion efficiency and based on them original concepts...
Savonius type wind turbine is considered suitable for power generation from low speed fluid flows i.e. canal and river systems. However it suffers from a poor efficiency. Lot of hydro potential in canal and rivers exists in India where Savonius type rotor as hydrokinetic turbine may be used. In order to minimize the static torque deviation and to enhance the performance of Savonius Rotor, continual...
A novel method of regulating the power generated by a tidal turbine is presented. The method makes use of the fact that the natural power coefficient curve of a turbine decreases monotonically with tip speed ratios above the maximum power point. Implementation of this method is discussed and results from simulations using GH Tidal Bladed are presented. The results show near-constant power output (with...
