چکیده

در این مقاله سیستم خورشیدی از نوع متمرکزکننده‌ای خورشیدی سهموی نقطه‌ای، مطالعه عددی و تجربی شده است. در کنار طراحی، ساخت و آزمایش کلکتور، سیستم در نرم‌افزار کامسول نیز مدل‌سازی شده است. آزمایشات و مدل‌سازی با استفاده از 2جاذب لوله‌ای مارپیچ و صفحه‌ای فین‌شکل در نقطه کانونی با 3دبی مختلف و در 2سیکل بسته و باز انجام شده است. مقایسۀ نتایج تجربی و شبیه‌سازی تطابق خوبی را بین آن‌ها نشان می‌دهد و میزان خطا بین 1 تا 4درصد است. نتایج نشان می‌دهد که جاذب نوع اول در مقایسه با جاذب نوع دوم کارایی بهتری دارد. همچنین با افزایش دبی راندمان کلکتور افزایش می‌یابد.

کلیدواژه‌ها
