How to improve the efficiency of vertical wind separator

Oct 31 2014 For instance Efficiency When the wind blows on the blades of a HAWT all of them contribute to energy production When wind blows on a verticalaxis turbine only a fraction of the blades generate torque while the other parts merely go along for the ride The result is comparably reduced efficiency in power generation

Product Introduction

Performance improvement of adaptive flap on flow

Flow separation on blades is the main factor to reduce the power efficiency of vertical axis wind turbine VAWT A bioinspired flow control device called adaptive flap is considered to have a good adaptability in mitigating the flow separation The present study investigated the adaptive flap in terms of improving its performance and exploring its effect on VAWT by the Computational Fluid Dynamics CFD method

Vertical axial cross flow type of wind turbines are considered to have superior characters in comparison with the conventional propeller type of HAWT ie operating as strong torque at starting

Feb 09 2018 This paper present experimental test results of separator and shift angle influence on Crossflow vertical axis wind turbine Modification by using a separator and shift angle is expected to improve the thrust on the blade so as to improve the efficiency The design of the wind turbine is tested at different wind speeds
