چکیده
Many investigators have presented mathematical work on desiccant wheels but there is a considerable discrepancy between published values and experimental values. A mathematical model based  on the two-dimensional  Navier-Stokes   equation has been derived to show the dehumidification trend of desiccant dehumidifier concerning air stream velocity. In this model the effect of air stream velocity on wheel performance as a momentum equation combined with heat and mass transfer has been studied. The current model is capable of predicting the transient and steady-state transport in a desiccant wheel. It reveals the moisture and temperature in both the airflow channels and the sorbent felt, in detail, as a function of time. The predicted results are validated against the data taken from experimental results, with reasonable accuracy. Therefore, the numerical model is a practical tool for understanding and accounting for the complicated coupled operational process inside the wheel. Consequently, it is useful for parameter studies.

عنوان مقاله [English]
یک رویکردی جدید برای انتقال حرارت و رطوبت در چرخ‌های جاذب دسیکنت بر مبنای سرعت جریان هوا
چکیده [English]
تاکنون بسیاری از محققین کار ریاضی روی چرخ های جاذب دسیکنت را ارائه کرده اند، اما اختلاف قابل توجهی بین مقادیر منتشر شده و مقادیر تجربی وجود داشته است. یک مدل ریاضی برای نشان دادن روند رطوبت‌زدایی جاذب رطوبت‌گیر دسیکنت با توجه به سرعت جریان هوا استخراج شده است. در این مدل تأثیر سرعت جریان هوا بر عملکرد چرخ به عنوان یک معادله اندازه حرکت همراه با انتقال حرارت و جرم مورد مطالعه قرار گرفته است. به این ترتیب یک مدل ریاضی بر اساس معادله دو بعدی ناویر-استوکس شرح داده شده است. مدل فعلی قادر به پیش بینی پدیده های انتقال گذرا و حالت پایدار در یک چرخ جاذب دسیکنت می باشد. این مدل رطوبت و دما را در کانال‌های جریان هوا و سطح جاذب با جزئیات به عنوان تابعی از زمان نشان می‌دهد. نتایج پیش‌بینی‌شده در برابر داده‌های به‌دست‌آمده از نتایج تجربی، با دقت معقول تأیید می‌شوند. بنابراین، مدل عددی ابزاری کاربردی برای درک و محاسبه فرآیند عملیاتی پیچیده درون چرخ است. در نتیجه، برای مطالعات پارامتر مفید است.
