| چکیده | ||
| استفاده از سیستم‌های ذخیره گرمای نهان با استفاده از مواد تغییر فازدهنده در سال‌های اخیر بسیار مورد توجه بوده است. استفاده از فین‌ها یکی از ساده‌ترین و ارزان‌ترین راهکارهای افزایش انتقال حرارت در ماده تغییرفاز دهنده و افزایش عملکرد سیستم ذخیره‌سازی است. با توجه به اینکه نحوه چیدمان فین‌ها در مدت زمان شارژ و در نتیجه راندمان انتقال حرارت تاثیر بسزایی دارد، هدف اصلی از این مطالعه، بهینه‌سازی چیدمان فین‌ها در محفظه ماده تغییرفاز دهنده در یک مبدل حرارتی دولوله‌ای، جهت کاهش زمان شارژ و در نتیجه افزایش راندمان سیستم ذخیره‌سازی انرژی است. برای این منظور معادلات حاکم شامل بقای جرم، بقای ممنتوم و بقای انرژی در یک مبدل حرارتی دولوله‌ای فین‌دار، با استفاده از نرم‌افزار انسیس-فلوئنت حل شده‌اند و رفتار حرارتی-سیالاتی ماده تغییرفاز دهنده و عملکرد سیستم ذخیره‌سازی مورد بررسی قرار گرفته است. همچنین برای یافتن بهترین چیدمان فین‌ها جهت بهینه‌سازی عملکرد ذخیره‌سازی، از روش سطح پاسخ و طرح مرکب مرکزی استفاده شده است. نتایج بدست آمده از سطح پاسخ با منحنی مرتبه سوم رتبه‌کاسته که از 25 شبیه‌سازی حاصل شده است، نشان می‌دهد در مقایسه با حالت بدون فین، چیدمان یکنواخت فین‌ها حدود 19% و چیدمان بهینه فین‌ها حدود 56% زمان شارژ را کاهش می‌دهد. | ||

| چکیده [English] | ||
| Using latent heat storage systems with phase change materials (PCM) is an effective way to store thermal energy, which has been of great interest in recent years. Using fins is one of the simplest and cheapest ways to increase heat transfer in PCMs and increase the performance of the storage system. Since the fin arrangement has a significant impact on the charging time of the PCM, the main goal of this study is to optimize the fin arrangement in the PCM chamber in a double-pipe heat exchanger to decrease the charging time, and thus increase the efficiency of the storage system. For this purpose, the governing equations, including conservation of mass, momentum, and energy in a finned double-pipe heat exchanger have been solved using ANSYS-Fluent software to investigate the thermal-hydraulic behavior of PCM. Also, to find the optimal fin arrangement and maximize the storage performance, the response surface method based on the central composite design has been implemented. The results obtained from the response surface with the reduced cubic equation show that compared to the case without fins, the charging time was reduced by 19% using the uniform fin configuration, while reduced by 56% using the optimal fin arrangement. | ||
