Abstract AR
تم في هذا البحث بناء أنموذج رياضي للجريان الادياباتي داخل الأنبوب الشعري و لمائعي التثليج (22-R و R-407C), باستخدام معادلات الاستمرارية و الطاقة و تمثيل هبوط الضغط خلال الأنبوب الشعري.
الأنموذج الرياضي يتضمن بناء أنموذج لمنطقة الجريان الأحادي الطور السائل و أنموذج آخر لمنطقة الجريان الثنائية الطور.
تم مقارنة النتائج الحسابية مع النتائج العملية المتوفرة في البحوث السابقة لغرض التحقق من صحة الأنموذج و إمكانية استخدامه لتحليل أداء منظومات التثليج الانضغاطية للوصول للامثلية.
Abstract EN
In this paper adiabatic flow in capillary tube is analyzed and modeled for R-22 and alternative R-407C.
The equations of continuity, energy and pressure drop through a capillary tube are presented.
A mathematical model of sub–cooled flow region and two–phase flow region is developed.
The results of the calculation compared with experimental data presented in the technical literature will be shown in the present article in order to validate the model developed.
This numerical model is capable of providing an effective means to analyze capillary tube performance to optimize and control an R–22 and R–407C in an air – conditioning systems.
