Appendix A
This section shows pitctures of the experimental setup for illustrative purposes.
A.1 Experimental Quasi-2D Fluidised Bed
Figure A.1 shows the quasi-2D fluidised bed in the present work. The quasi-2D cell
is constructed of acrylic glass with a width of 45 cm, a thickness of 1 cm, and a
length of 80 cm. The planar cell is connected to a 20 cm long plenum chamber.
A.2 Gas Flow Calibration Setup
Figure A.2 shows the calibration setup used for calibrating the volumetric flow
meters. The OMEGA Venturi flow meter was calibrated using a FLUICAL portable
mass flow meter calibrator. The calibration was carried out under different supplied
gas pressures, and repeated three times on different days. The calibration was then
confirmed independent of supplied air pressure.
The supplied gas temperature could affect calibration. This mass flow meter
calibrator functions by heating up the passing air, and then detecting the voltage
signal caused. Therefore, it assumes an operation under normal conditions (15 °C
and 1 bar). Considering the calibration was carried out at a room temperature around
20 °C:

ρ T =288K
ρ T =288K
ρ T =293K

ρ T =288K
ρ T =293K
∼ 1.017V reading
where V reading is the reading of the mass flow meter, and V real is the actual flow rate.
