Abstract AR
تم عمل دراسة معملية لبيان أداء انتقال الحرارة لسيفون حراري مغلق مهتز و كان مائع التشغيل المستخدم هو R134a.
تم دراسة تأثير الفيض الحراري (W / m2 6331 ≤q≤ (1276W /m نسبة الامتلاء (% 100>+30 % و وجد أن أفضل نسبة امتلاء و تردد اهتزازي لا بعدى هي % 50 و 1.448 على الترتيب. و تم الوصل إلى علاقة لا بعدية لرقم توصلت كدالة في رقم كوتاتيليدزيا، و نسبة الامتلاء، و نسبة التردد اللابعدى، و سعة الاهتزازة اللابعدية و كذلك نسبة الضغط.
Abstract EN
An experimental investigation had been carried out in order to study the heat transfer performance of a vibrated two-phase closed thermosyphon tube.
The working fluid used was R143a.
The effects of heat flux (1276W / m2 ≤ q ≤ 6331W / m2), filling percentage (30 % ≤ V + ≤ 100 %), the vibration dimensionless frequency (1.08 ≤ F ≤ 3.26), and the dimensionless amplitude (0.19 ≤ B ≤ 0.57) were studied.
It was found that, the optimum filling percentage and the best dimensionless frequency values are 50% and 1.448 , respectively.
The Nusselt number had been correlated in a dimensionless form as a function of Kutateladze number, filling ratio, dimensionless frequency, dimensionless amplitude, and reduced pressure ratio.
