چکیده

تاکنون پژوهشهای آزمایشگاهی زیادی در زمینۀ قرار دادن انواع مانع جریان در کلکتور خورشیدی انجام شده‌است اما تأثیر استفاده از مانع نوار تابیده داخل کلکتور یک واحد فتوولتاییک حرارتی انجام نشده که برای اولین بار در این پژوهش به‌صورت آزمایشگاهی صورت میگیرد. ده نوع نوار تابیده برگرفته از تحقیقات پژوهشگران در گذشته که دارای بالاترین کارایی نسبت‌به سایر موانع جریان در داخل لوله بودند به‌منظور بررسی و تعیین بهترین نوار انتخاب شدند. باتوجه به هزینه‌های بالای مواد و لوازم مصرفی، تجهیزات مورد نیاز، تولید نوارهای تابیده و انجام آزمایش‌ها، بررسی نوارهای تابیدۀ مذکور برای انتخاب بهترین نوار تابیده به‌صورت عددی انجام خواهد شد؛ لذا به‌منظور صحه‌گذاری مدل‌سازی عددی، بستر آزمایشگاهی برای انجام آزمایش‌های لولۀ صاف بدون/با نوار تابیدۀ ساده آماده گردید. پس از صحه‌گذاری مدل عددی، بررسی عددی 10 نوع نوار تابیدۀ منتخب (با اشکال مختلف) در شرایط یکسان انجام و بهترین نوار تابیده (دارای بالاترین کارایی) انتخاب شد. درنهایت، نوار تابیدۀ منتخب در لولههای کلکتور( مدل هدر- رایزر) واحد فوتوولتاییک حرارتی جای‌گذاری و اثر آن به‌صورت آزمایشگاهی با شبیه‌ساز خورشیدی ارزیابی گردید.

چکیده [English]

So far, many experimental researches have been done in the field of placing various inserts in the solar collector, but the effect of using the twisted tape insert inside the collector of a thermal photovoltaic unit (PV/T) isn’t done and for the first time in this research it is accomplished experimentally. Last researches were investigated to determine which type of twisted tapes had the highest efficiency. Meanwhile, ten types of twisted tape inserts were selected to evaluate. Due to the high cost of materials needed to fabricate twisted tapes, the evaluation of the ten twisted tapes was performed numerically. Therefore, in order to validate numerical modeling, an experimental apparatus was prepared to perform smooth tube experiments without / with a simple twisted tape. After validating the numerical model, numerical examination of ten selected twisted tapes (with different shapes) was carried out in the same conditions and the best one (with the highest efficiency) was selected. Finally, the best twisted tape insert was placed in the collector tubes (header-raiser model) of the PV/T system and its effect was evaluated using indoor experimental tests.
