Abstract AR
يهدف هذا البحث أساسا للتنبوء بالتدفق الحراري الحرج داخل أنابيب ساخنة مع استعمال ضغط 0.1 الى 0.7 ميغا باسكال (MPa).
في هذه الدراسة استعملنا 742 نقطة تجريبية للتدفق الحراري الحرج لأنابيب ذات طبقة مسامية.
دقة المعادلات تم تقديرها بحساب الخطأ النسبي المتوسط و المتوسط الحسابي.
كما تم اقتراح معادلة للتنبؤ بالتدفق الحراري الحرج للأنابيب ذات الطبقة المسامية.
Abstract EN
This paper includes the prediction of critical heat flux (CHF) for uniformly heated vertical porous coated tubes at pressures between 0, 1 to 0,7 MPa.
In this study, we use a total of 742 data points of CHF for water in uniformly heated vertical porous coated tubes obtained from literature.
Accuracy of correlations was estimated by calculating both the average and RMS error with available experimental data, and a new correlation is presented.
The new correlation predicts the CHF data with average error 0.07 % and RMS error 7.91 %
Abstract FRE
L’article étudie la prédiction du flux de chaleur critique (FCC) pour les tubes enrobés, poreux et verticaux uniformément chauffés à des pressions entre 0.1 et 0.7 MPa.
Dans ce travail, un total de 742 points de données de FCC (flux de chaleur critique) a été utilisé.
L’exactitude des corrélations a été estimée en calculant l’écart relatif et l’écart_ type avec des données expérimentales.
Une nouvelle corrélation est présentée et elle prédit les conditions de FCC avec une erreur relative moyenne 0.07 % et un écart type 7.91 %.
