Abstract AR
أجريت تجارب لدراسة عملية انتقال الحرارة بالحمل الحر في أسطوانة دائرية مائلة مسخنة تسخين منتظم.
تم مناقشة تأثيرات الفيض الحراري للسطح و زاوية الميل على تغيرات درجة الحرارة و رقم نسلت الموقعي خلال سطح الأسطوانة.
غطت الدراسة مدى الفيض (عمودي).
بينت النتائج بأن الحمل الحر يزداد 90°، و 60°، 30° (أفقي)، 0° الحراري من (92 إلى 487) واط / متر مربع و زاويا ميل كلما زاد الفيض الحراري و كلما تغيرات زاوية الميل من الوضع العمودي إلى الوضع الأفقي.
تم استنباط معادلة تجريبية لمعدل رقم نسلت كدالة لرقم رايلي لكل زاوية ميل.
Abstract EN
Experiments were carried out to investigate natural convection heat transfer in an inclined uniformly heated circular cylinder .
The effects of surface heat flux and angle of inclination on the temperature and local Nusselt number variations along the cylinder surface are discussed .
The investigation covers heat flux range from 92 W/m² to 487 W/m², and angles of inclination 0° (horizontal), 30°, 60° and 90° (vertical).
Results show an increase in the natural convection as heat flux increases and as angle of inclination moves from vertical to horizontal position.
An empirical equation of average Nusselt number as a function of Rayleigh number was deduced for each angle of inclination.
