چکیده | ||
Convective heat transfer from a flat plate, which is enhanced by an oscillating blade, was numerically investigated at the present study. It was assumed that the blade is made of a rigid and thin plate and it is vertically oriented at the top of the target plate. Numerical analysis was performed using commercial software ANSYS Fluent 6.3 and the periodic oscillation of the blade was modeled by the moving mesh method. Conservation equations of mass, momentum and energy was solved in 2-D and transient form for the laminar airflow with constant physical properties. Constant temperature was considered for the plate and the details of both the flow and thermal fields were determined. The distribution of convective heat transfer coefficient was then calculated for the target plate. The effect of various parameters including the amplitude and frequency of the blade oscillation as well as the geometrical parameters was investigated on the convective heat transfer from the target plate. The results indicated that a wider area of the plate was affected by increasing the oscillation amplitude of the blade. Convective heat transfer was also enhanced over the entire target plate as the rotational Reynolds number was increased. | ||

تحلیل عددی انتقال حرارت کنوکسیونی از یک صفحه تخت بر اثر نوسان یک تیغه عمود بر صفحه | ||
چکیده [English] | ||
انتقال حرارت کنوکسیونی از یک صفحه تخت که بوسیله نوسان یک تیغه تشدید می شود بصورت عددی در این مقاله مورد بررسی قرار گرفته است. تیغه مورد استفاده یک صفحه نازک و صلب فرض می شود که بصورت عمود بر سطح صفحه هدف و در بالای آن قرار گرفته است. تحلیل عددی با استفاده از نرم افزار فلوئنت 6.3 صورت گرفته و حرکت نوسانی تیغه به کمک روش مش متحرک مدل سازی شده است. معادلات بقای جرم، اندازه حرکت و انرژی در حالت گذرا برای جریان آرام با خواص فیزیکی ثابت حل شده است. دمای ثابتی برای صفحه منظور شده و جزئیات میدان های جریان و دما بدست آورده شده است. بر اساس میدان دمای حاصل شده، تغییرات ضریب کنوکسیونی انتقال حرارت روی صفحه محاسبه گردیده است. تاثیر پارامترهای مختلف شامل دامنه و فرکانس تیغه نوسان کننده همچنین پارامترهای هندسی بر روی توزیع ضریب کنوکسیونی روی صفحه برخورد بررسی شده است. نتایج نشان داده که با زیاد شدن دامنه نوسان تیغه، سطح وسیع تری از صفحه برخورد تحت تاثیر قرار گرفته است. همچنین شدت انتقال حرارت روی صفحه برخورد با اضافه شدن عدد رینولدز دورانی افزایش یافته است. | ||
