Abstract AR
أن تحسين انتقال الحرارة العوائق قد درس عدديا و عمليا.
عمليا، لقد درس إمرار هواء ساخن خلال مجرى m3 (0.04* 0.16*1.15) مع ترتيب مختلف.
ترتيبات العوائق هي سفلي 12، علوي 12، و متخالف 24.
الترتيب المتخالف أعطى أفضل أداء.
كذلك درست زاوية الهجوم للترتيب السفلي و للزوايا 45، 60، 90 و قد وجد أن أفضل أداء كان ل 60.
عدديا تم حل معادلات حفظ الكتلة و الطاقة بواسطة طريقة الحجوم المحددة لجريان هواء خلال مجرى (1.15 * 0.16*0.04) m3.
النتائج العملية قورنت مع النتائج العددية لتدقيق البرنامج الحاسوبي و قد كانت المقارنة مقبولة.
ثم مددت النتائج العددية لتشمل حالة جريان الهواء البارد خلال مجرى ساخن.
Abstract EN
The rib enhancement of heat transfer in a duct is studied numerically and experimentally, where hot air passes through a duct (0.04 x 0.16 x 1.15 m3) with different rib arrangement.
The armaments are lower 12-rib arrangement; upper 12 rib arrangement and 24 rib staggered arrangement.
The staggered arrangement gives better performance than the others.
Also, the angle of attack was studied for lower arrangement, three different values were tested (45°, 60° and 90°).
Angle of 60°gives better performance.
Numerically, the three-dimension continuity, Navier-Stokes and energy equations are solved by finite volume method of flow of air through (0.04 x 0.16 x 0.6 m3).
Validation of the code was performed by comparing the numerical result with the results obtained experimentally for staggered arrangement only.
The agreement seems acceptable.
The numerical studies were extended to study the case of cold air passing through hot ribbed duct.
