چکیده

در این پژوهش به محاسبه زمان راه‌اندازی یک میکرو توربین بادی پرداخته می‌شود. به این منظور از نظریه‌ی اندازه حرکت المان پره استفاده شده و پس از صحت سنجی کد تهیه شده، پارامتر زمان راه‌اندازی محاسبه می‌شود. سپس با توجه به محدودیت کاری رینولدز، چهار ایرفویل NACA4412، SD7062، SG6040 و SG6043 انتخاب و اثر بهره‌گیری از آن‌ها بررسی می‌شود. نتایج نشان می‌دهد استفاده از ایرفویل SG6043 نه تنها توان بیشتری را به همراه داشته بلکه زمان راه‌اندازی کمتری نیز دارد. نسبت بالای برآ به پسآی ایرفویل SG6043 به همراه کم بودن مساحت سطح از عوامل اصلی برتری این ایرفویل می‌باشد.
