Abstract AR
أجريت دراسة عملية و نظرية لانتقال الحرارة من أوجه مكعب معرض لنفث موجه إلى الوجه العلوي للمكعب.
المكعب معرض كذلك لجريان جانبي ذو سرعة قليلة نسبيا خلال المجرى الذي يحوي المكعب.
لقد درست العوامل المؤثرة على عملية التبريد مثل حجم المنفث، سرعة المنفث و المسافة العمودية بين المنفث و المكعب.
أظهرت النتائج أن الجربان الجانبي يزيد انتقال الجرارة من المكعب لأحجام المنفث الصغيرة و لسرع المنفث الصغيرة.
أحجام المنفث التي تساوي أو التي اكبر من حجم المكعب سوف تعزل المكعب عن الجريان الجانبي و خاصة لسرع النفث العالية.
Abstract EN
An experimental and numerical investigation is carried out for the heat transfer from a cube faces subjected to impinging jet which centrally strikes the top face of the cube.
The cube is subjected also to a comparatively low velocity cross flow through the duct occupying the cube.
Different factors affecting the cooling characteristics of the cube are studied as orifice size, jet velocity and orifice to cube top distance.
The results show that cross flow increases heat rates from the cube for small size orifices and low impinging jet velocities.
Orifice sizes equal or bigger than cube size will isolate the cube from cross flow effect especially at high impinging jet velocities.
