Abstract
Using a Venturi to Capture and increase wind velocity are carried out to enhance the performance of wind turbines, the Idea of Ducted Wind Turbines has been an interest because of the ability to increase the velocity through them, the results of multi physics simulations involving Computational Fluid Dynamics, used to evaluate a highly acclaimed innovative wind power generation system known as INVELOX, are presented. This patented technology significantly outperforms traditional wind turbines, and it delivers superior power output, reflecting an idea of wind power plant in the urban Areas where wind velocity is low, so increased wind velocities throughout the INVELOX System and the Venturi resulted in significant improvement in the Kinetic Energy hence power output of Turbine. In addition, INVELOX technology brought an idea of retrofitting the traditional horizontal axis windmills to adapt the Innovative INVELOX design at reduced cost. Furthermore, the new design claiming the ability of solving all the major issues, such as low turbine reliability, intermittency issues, adverse environmental and radar impact that have so far undermined the wind industry. The goal in this thesis divided into two sections, section one I will try to examine the possibility to capture, accelerate and concentrate the wind by creating a simple prototype of a ducted wind turbine with a ratio of 1:20 with the new INVELOX design system to validate the feasibility of retrofit those traditional wind turbines. Second is test results will be measured from a fielded unit, the results will be compared with those obtained by using the bare INVELOX technology, both velocities at Intake and Venturi positions will be compared in this analysis. In more studies that are recent and in other thesis work the Actual concentration was on the INVELOX technology, the studies used computational fluid dynamics but never measured from a fielded unit, the performance of the system was validated by recent measured field data by the company itself. My Field test of a simple prototype Ducted Wind Turbine showed that the increase in wind speed maintained even with speeds as low as 2.5 m/s, and thereby energy production can be significantly improved. This measured data shown to be consistent with that obtained through full-scale computational fluid dynamics models and other research work. Further lab testing is recommended to confirm the velocity developing with an actual turbine being inserted.
