With the present advancement, a wind turbine needs rotor with high torque and power. The study aims to enhance power of by employing ducted dual rotor. In this regard, CFD analysis is performed analyze produced for horizontal axis single bare turbine, convergent-divergent type turbine. comparative conducted aforementioned type. results highlight maximum value 36.9% more than at 16 m/s velocity ...

Design and manufacturing of a high performance micro-hydro-kinetic turbine is discussed in the present paper. The main goal is manufacturing an equipped experimental model of hydro-kinetic turbine with highest energy absorption from water current. A multi-shape ducted turbine comprised of a multi-part diffuser was manufactured that can be converted to many experimental models for studying vario...

Abstract. The aerodynamic design of a ducted wind turbine for maximum total power coefficient was studied numerically using the axisymmetric Reynolds-averaged Navier–Stokes equations and an actuator disc model. characterizes rotor per device area rather than area. This is useful metric to compare performance with open can be important objective in certain applications. variables included duct l...

This paper analyses the dynamics loads exerted by waves on a floating offshore platform in Straits of Messina, (South Italy), hosting an innovative ducted wind turbine. The force largest sea occurring during lifetime are predicted quasi-determinism theory, which foresees what happens if group exceptionally large height occurs at given point sea.
