description |
An experimental investigation has been performed, studying hydrodynamics behaviour
of two-dimensional bubbling in a gas-solid fluidized bed with a CCD high speed
camera. The main focus for analysing on the influence of varies pressure and particle
size towards the bubble diameter bubble density, bed expansion and bubble rising
velocity.
A method has been implemented to verify that the image recording scheme yielded
reproducible time-averaged flow patterns. The high speed camera with a speed up to
3,000 frames per second was placed in front of the rectangular column to observe the
hydrodynamics behaviour. Image analysis software was used to analyse the image that
allows determination of bubble characteristics.
Bubble diameter will increase with height above air distributor until it reaches maximum
bubble height, h*, beyond which bubbles do not grow further and become unstable and
break up. The maximum bubble height, h* is a minor effect on differential particle size
and pressure. Bubble density increase with particle size at low pressure and decrease
with particle size at high pressure. The bed expansion increases with pressure and
decrease with particle size. |
