Abstract

The aims of the present research study the pressure drop and the parameter that effect on it in the two type of multi-phase upward flow system (fixed bed and fluidized bed ) and used the solids as dense phase such as glass beads with diameter 6 mm and Rashing ring with 6 mm equivalent diameter and distilled water as moving phase with change in temperature of moving phase for four-level (20, 30, 40 and 50)?.
Used design of experimental to give the all conditions of the experimental runs and carried out in experimentally in the cylindrical column made from Perspex with 5 cm ID and 6 cm OD and 1m length with two holders one put in the basic of packed bed and another used to prevent the particles from carried out with moving phase in the fluidized bed and used to make the bed in stationary state in the fixed bed. Where fixed on the wall of the column six pressure sensor transducer put the first at the basic of the packed bed and each 10 cm put the other one for six sensors and connected to the Arduino cart and used LabVIEW program to display and save the data of pressure sensors readings.
And the experimental result of fluidized bed comparewith the fixed bed and it was observed the pressure drop effect by the change in the shape of dense phase and temperature of moving phase, where the pressure drop decrease with increase in diameter of dense phase also decrease with change in the shape from sphere to Rashing ring and increase with increase in temperature.
To make sure the data taken from the experimental work makes validation with many theoretical equations and empirical design model and gives a good agreement.
