Abstract: | The experimental study of vertical jet in a two-dimensional fluidized bed is presented. The time series of vertical jet penetration
depth are acquired by image processing. The fluctuation of jet which is studied by means of Hurst’s analysis becomes weaker
with increase in jet velocity, fluidization number, particle diameter and static bed height. They are found that the signal
is persistent and the fractal dimensional of vertical jet is between 1. 19 and 1. 64.
