چکیده

تولید صدا توسط توربین‌های بادی محور عمودی می‌تواند از محبوبیت آن‌ها برای به کار بردن در مناطق شهری و مسکونی کم کند. به‌منظور کاهش سطح صدای تولیدشده، در این مقاله، رفتار آکوستیکی روتور ترکیبی با کمک دینامیک سیالات محاسباتی ((CFD)Computational Fluid Dynamics) مطالعه شده است. در ساختار روتور مورد بررسی، از پره‌های نوع متعارف ساونیوس به‌عنوان روتور داخلی استفاده شده که با زاویۀ صفر درجه به روتور خارجی متصل شده است. برای اطمینان از مدل‌سازی، اعتبارسنجی نتایج و تأثیر گام زمانی بر داده‌های خروجی صورت گرفته است. هدف از این پژوهش، بررسی تأثیر نسبت سرعت نوک و سرعت آزاد باد بر میزان سطح صدای تولیدشده است. نتایج نشان دادند که سطح صدای تولیدشده رابطۀ مستقیم با نسبت سرعت نوک و سرعت آزاد باد دارد، به این صورت که کمترین سطح فشار صوت در نسبت سرعت نوک 5/1 و سرعت آزاد باد 5 متر بر ثانیه توسط دریافت‌کنندۀ R4 گزارش شده و مقدار آن برابر 64/7 دسیبل است. همچنین با دور شدن از روتور سطح صدای تولیدشده کاهش می‌یابد.
