چکیده

با توجه به اینکه شکل و چیدمان حفره‌های آجر، تأثیر زیادی بر میزان انتقال گرمای نفوذی به داخل ساختمان دارد، بنابراین لازم است که مدل‌های مختلف این حفره‌ها مورد بررسی قرار گیرد. در تحقیق حاضر، به ارائه ساختار جدیدی برای سلول‌های آجر ساختمانی پرداخته شده و تأثیر شکل و ابعاد حفره‌ها بر عملکرد گرمایی آن با استفاده از روش المان محدود و روش پاسخ سطح رویه (RSM) مطالعه شده است. پارامترهای ورودی شامل مشخصات هندسی حفره‌ها بوده و عبور گرما به عنوان متغیر پاسخ در نظر گرفته شده است. به منظور حداقل کردن پارامتر انتقال گرما، روش RSM و المان محدود به صورت همزمان استفاده شده است. معادلات انتقال گرمای سه‌بعدی به صورت پایا و در نظر گرفتن سه مکانیزم انتقال گرمای رسانشی، همرفتی و تابشی حل، و توزیع دما و ضریب رسانایی گرمایی تعیین شده است. نتایج نشان می‌دهند که با افزایش ضخامت جداره یا با افزایش ارتفاع حفره و به طور کلی با افزایش محیط حفره می‌توان مقاومت گرمایی بلوک‌ها را افزایش داد. نتایج نشان می‌دهد که در بین طرح‌های بررسی شده، بهترین عملکرد گرمایی مربوط به نمونه HB-10 با U-value برابر 95/1 می‌باشد که بهبود 97% نسبت به آجر بدون حفره پیدا کرده است.
