	1	Magnetic resonance studies of a gas-solids fluidised bed:Jet-jet and jet-wall interactions显示文摘Magnetic resonance imaging(MRI)gave images of air jets from orifices in the distributor plate of a bed of poppy seeds.Attention focused on two features:(1)The interaction between nearby vertical jets from two,three or four orifices;(2)Wall effects,where one or more orifices created vertical jets near the vertical wall of the cylinder containing the particle bed.The results show that nearby jets are mutually attracted.Likewise a jet near a wall bends out of the vertical,towards the wall.For multiple adjacent jets,the jet lengths show dependence on orifice layout:the lengths are in reasonable agreement with published measurements,by other methods,for single jets.The MRI gives three-dimensional images of the single jets and of multiple jets,separate or merging.

	2	Gas flow in rotary kilns显示文摘This paper describes an experimental investigation on the flow characteristics within a rotating cylinder containing a rolling bed of sand.The axis of the cylinder was horizontal and there was no axial bulk flow of particles.The velocity field of the gas flowing through the cylinder was measured by hot-wire anemometry.The measurements indicate that the velocity field is asymmetric with respect to a diameter perpendicular to the granular bed.CFD calculations confirm this finding.The gas velocity profiles are crucial in determining heat transfer from gas to solid.
