CFD Investigation and Aerodynamic Analysis of a Small-Scale Horizontal Axis Wind Turbine Performance Customized to Suit the Climate Conditions of Mosul City
Main Article Content
Abstract
This paper offers detailed CFD research and aerodynamics of a small-scale HAWT relevant to the meteorological circumstances in Mosul City. This current work shows the best way of building a wind turbine blade using the BEM Theory as the basis. The blade was subdivided into twenty parts along the blade span to form the elements of the blade. The chord length and twist angle distributions over the span were estimated at each section normal to the blade length. Findings show effectiveness in the enhancement of energy retrieval and system stability, thus proving the possibility of optimizing turbines for renewable energy production in the city environment. As highlighted in the CFD findings conditions, the power coefficient is related to the incoming wind speed at a constant rate of the rotor speed. The power coefficient increases with the tip speed ratio up to a certain point, after which it decreases and eventually approaches zero as the tip speed ratio continues to rise. The power coefficient is maximum at a value of 0.35 at a tip-speed ratio of 3.5. As a result of the present design of HAWT, it offers the ability to operate in the low-speed wind regions.
