✦ Synopsis

AbstrW

-An experimental study is described of Ihe behaviour of Synclyst particles (do, = 48pm) fluidised by air in a 0.05 m i.d. column; pressures in the range 1-22 bar were used. The expansion of the dense phase during bubbling is compared with maximum bed expansion before bubbling. The data are used to estimate the possible effect of Taylor instability on bubble-break-up at high pressure.

A study is reported on the "bed support experiment" in which measurements of the minimum supporting velocity are performed for a wide range of conditions. Values of the drag coefficient for the particles at the upstream end of a packed bed are then calculated, and the data are seen to be well repres

The expansion of gas-liquid fluidized beds has been measured for beds of glass ballotini fluidized by air/water. Particle diameters varied from 0.28 to 2.2 mm, and settled bed heights from U-107 cm. The flow rates of air and water were varied independently. The expansion of a liquid fluidized bed i
