This paper described the visualization on the behavior of bubbles near a blowing nozzle in a pressurized fluidized bed. Experimental study for understanding the characteristics such as the size and interval period of bubble nucleus in the pressurized gas fluidized beds were carried out with recording image pictures taken by high speed video camera (HSV-1000). As the results from image analysis we found the bubble size decreased and the bubble shape varied with the pressure increased, also seemingly the bubble shape was strongly influenced by particle size and the bubble frequency slightly increased with pressure incseased. Also a history of bubble growth was shown clearly.
