Abstract AR
نظام الطور الثلاثي (غاز-سائل-صلب) في مفاعل العجينة السائلة تطبيقات صناعية واسعة.
و مفاعل العجينة السائلة عبارة عن وعاء يحتوي على العامل المساعد بشكل عالق في الطور السائل.
في هذه الدراسة تم تطوير موديل رياضي (ديناميك الموائع الحسابي) يتم من خلاله حساب معدل احتجاز الغاز داخل العمود عند سرع مختلفة للغاز.
و تم قياس معدل احتجاز الغاز عمليا أيضا و تم مقارنة نتائج الموديل مع النتائج العملية و وجدت المقارنة بينهما جيدة.
كذلك تم استنتاج معادلة تجريبية لمعدل احتجاز الغاز و تم مقارنتها مع النتائج العملية بمعامل ارتباط 0.994.
Abstract EN
Gas-Liquid-Solid system as slurry in a reactor have a wide range of applications in industry, a slurry reactor is a vessel containing the catalyst suspended in a liquid phase.
In this study, we develop a CFD model to predict the gas holdup at different gas superficial velocities.
The experiments were done in a gas-liquid-solid slurry bubble column to find the gas holdup (eG).
The experimental data showed a good agreement with CFD results.
An empirical correlation has been developed to predict the gas holdup for three-phase slurry with a correlation co-efficient of 0.994; this correlation shows that the gas holdup predicted was in good agreement with experimental values.
