The Department of Chemical Engineering at the University of Technology discussed a master's thesis on the hydrodynamic properties of a fluidized bed reactor using three non-Newtonian phases, liquid and gaseous solid.

The thesis of student Zahraa Salman Hassan aimed to clarify the effect of the non-Newtonian behavior of the fluid on the hydrodynamic properties of a three-phase reactor (gas - liquid - solid) under different operating conditions for gas velocity values ​​(2, 4, 6) cm/sec, fluid velocity (0.9, 1.39, 1.8, 2.3) cm/sec, and the recycling ratio (1.5, 2, 2.5). The study observed the effect of non-Newtonian behavior using polymethyl cellulose (PMC) at different concentrations (0.1, 0.2, 0.3 and 0.4) wt.

The results showed that the higher the gas velocity, the lower the liquefaction velocity, while it increased with the increase in the non-Newtonian behavior. Increasing the recycling rate leads to a decrease in the minimum fluidization velocity, the increase in gas retention coincided with an increase in the liquid flow rate increases the liquid retention values, while it decreases with the increase in gas velocity, the solid failure decreases with an increase in the gas velocity at a constant liquid rate. Similarly, for a continuous gas velocity,

The discussion committee consisted of

Prof. Dr. Jamal Mane’ Ali, as head, and as a member of Prof.Dr. Amer Aziz Abdel Rahman, Prof.Dr. Musab Kazem Rasheed, and under the supervision of Prof.Dr Asawer Abdel Rasoul Kouiri and Prof. Dr. Zainab Youssef Shaneen.

As well as the scientific evaluation of the thesis by Prof. Dr. Saleh Abdul-Jabbar Saleh from the University of Al-Qadisiyah and Prof.Dr. Raed Tariq Hadi from the University of Al-Muthanna, and linguistically by Prof.Dr. Farouk Ahmed Mahdi from the University of Technology.
