بررسی اثر گردابه ها بر راندمان توربین باد محور عمودی
سال: 2014
خلاصه:
انرژی باد می تواند به عنوان گزینه ای پایان ناپذیر و برای تامین مصارف بشر مورد استفاده قرارگیرد. توربین های بادی راه حل امید بخشی را برای مناطق دور از شبکه عرضه می کنند. توربین داریوس یکی از انواع توربین ها است که اگر با ...
Numerical study of airfoil thickness effects on the performance of J-shaped straight blade vertical axis wind turbine
سال: 2016
خلاصه:
Providing high starting torque and efficiency simultaneously is a significant challenge for vertical axis wind turbines (VAWTs). In this paper, a new approach is studied in order to modify VAWTs performance and cogging torque. In this approach, J...
A numerical study on the aerodynamic performance and the self-starting characteristics of a Darrieus wind turbine considering its moment of inertia
سال: 2017
خلاصه:
Self-starting characteristics is a challenging issue in the field of Darrieus-type vertical axis wind turbines. Traditionally, the numerical simulations were performed at several constant rotational velocities for the ...
