In this paper four phase fluidized bed is experimentally built and numerically modeled to study the bed characteristics such as ratio (the static bed height of solid particle / the bed diameter (H/D)), air, gasoline , and water superficial velocity. The test pipe for the experimental rig is Perspex pipe with 1 m long and 0.0254 m diameter. The 2D numerical model has been established with Ansys fluent 15.0. Pressure drop equation is found to relate the pressure drop with the bed parameters with

... eviation of 22%. The Four-phases was represented by air, water, gasoline and solid particle. The results show that the pressure of the bed increases as the ratio H/D increases and air, gasoline , and water superficial velocity increases. As well as the expansion of the bed increases as air, gasoline, and water superficial velocity increases. ‫الخالصة‬ ‫ا‬ ‫تفاع‬ ‫ار‬ ‫(نسبة‬ ‫الطور‬ ‫باعي‬ ‫ر‬ ‫التمييع‬ ‫أنبوب‬ ‫اص‬ ‫خو‬ ‫اسة‬ ‫در‬ ‫تمت‬ ‫البحث‬ ‫ىذا‬ ‫في‬ (‫االنبوب‬ ‫قطر‬ / ‫الصمبو‬ ‫لماده‬ H/D ‫سرعو‬ ,) ‫و‬ ‫اء‬ ‫اليو‬ ‫مادة‬ ‫من‬ ‫عمميا‬ ‫المستخدم‬ ‫األنبوب‬ .‫يا‬ ‫نظر‬ ‫نموذج‬ ‫بناء‬ ‫و‬ ‫عمميا‬ ‫الطور‬ ‫باعي‬ ‫ر‬ ‫تمييع‬ ‫أنبوب‬ ‫بناء‬ ‫خالل‬ ‫من‬)‫الكازولين‬ ‫و‬ ‫الماء‬ (Perspex ‫بطول‬) 1 ‫و‬ ‫م‬ ‫قطر‬ 2.20.0 (‫نامج‬ ‫بر‬ ‫باستخدام‬ ‫األبعاد‬ ‫ثنائي‬ ‫نظري‬ ‫نموذج‬ ‫أنشاء‬ ‫تم‬ .‫م‬ Ansys fluent 15.0 ‫تم‬ ‫كذألك‬ .) ‫حيود‬ ‫وبنسبة‬ ‫األنبوب‬ ‫اص‬ ‫خو‬ ‫عمى‬ ‫باالعتماد‬ ‫لألنبوب‬ ‫الضغط‬ ‫فرق‬ ‫لحساب‬ ‫يبيو‬ ‫تجر‬ ‫معادلة‬ ‫إيجاد‬ 00 ‫االطو‬ .% ‫ىي‬ ‫المستخدمو‬ ‫ار‬ ‫و‬ ‫الماء‬ ‫و‬ ‫اء‬ ‫اليو‬ (‫النسبة‬ ‫يادة‬ ‫بز‬ ‫يزداد‬ ‫األنبوب‬ ‫ضغط‬ ‫بان‬ ‫النتائج‬ ‫بينت‬ .‫الصمبو‬ ‫الحبيبات‬ ‫و‬ ‫الكازولين‬ H/D ‫الكازولين‬ ‫و‬ ‫اء‬ ‫اليو‬ ‫وسرعة‬) ‫و‬ .‫الماء‬ ‫و‬ ‫الكازولين‬ ‫و‬ ‫اء‬ ‫اليو‬ ‫سرعة‬ ‫يادة‬ ‫بز‬ ‫يزداد‬ ‫األنبوب‬ ‫داخل‬ ‫الصمبة‬ ‫المادة‬ ‫تفاع‬ ‫ار‬ ‫فان‬ ‫ذلك‬ ‫إلى‬ ‫باإلضافة‬ .‫الماء‬
