چکیده مقاله:
The current research illustrates the optimization of Vertical Axis Wind Turbine (VAWT) blades with implementation of added winglets displaying improved self-starting capabilities. The application of improved design is to be utilized in a university campus located in United Arab Emirates (UAE) in order to reduce its margin of consumed electrical energy by ۱۵%. The study is conducted over a mean wind speed value of ۵ m/s achieved in a one-year period at a specific altitude of ۵۰ m in the UAE. Two aerodynamic simulation software were adopted, namely ANSYS FLUENT CFD and QBlade, with designs being modelled using AutoCAD. The analytical analysis included some aerodynamic characteristic such as power, lift, and drag coefficients. Through ۲D-computational fluid dynamics (CFD), simulation study tested ۲۰ different symmetrical as well as asymmetrical airfoils including the cambered S-۰۱۴۶ with ۲۶.۸۳% higher power output and lower noise amongst the test subjects. Turbine torque for added winglet design results in ۴.۱% higher compared to the benchmark. The modified design aims to produce at least ۲% more power and have an improvement in self-starting of at least ۲۰%. VAWTs tend to have higher potential and sensitivity towards wind direction (no yawing mechanism required) illustrating them as more cost-effective. Future scope includes utilizing wind lens technology to increase the free-stream velocity.
