Abstract AR

تمت دراسة نسب التارجح و التمدد للابراج المميعة الأسطوانية نوع غاز – صلب لمادة الباراسيتامول باستعمال الهواء، حيث ان المتغيرات كانت اقطار الأبراج المميعة (0.0762، 0.15و 0.18 متر)، الأرتفاع الأستاتيكي للطبقة المميعة (0.07، 0.05 و 0.09 متر) و سرعة الهواء لعدة مرات اكبر من سرعة التمييع الدنيا.

لوحظ أن كلا من نسبة التارجح و التمدد لها علاقة طردية مع سرعة الهواء و عكسية مع قطر العمود و ارتفاع الطبقة.

لوحظ تطابق جيد ما بين النتائج العملية مع القيم النظرية.

Abstract EN

The fluctuation and expansion ratios have been studied for cylindrical gas-solid fluidized columns by using air as fluidizing medium and Paracetamol as the bed material.

The variables were the column diameter (0.0762, 0.15, and 0.18 m), static bed height (0.05, 0.07, and 0.09 m), and air velocity to several times of minimum fluidization velocity.

The results showed that both the fluctuation and expansion ratios had a direct relation with air velocity and an inverse one with column diameter and static bed height.

A good agreement was between the experimental results and the calculated values by using the correlation equations from the literature.
