The behavior of gas bubbles and particles in fluidized-beds which cause the fluctuations of gas velocity, pressure and temperature are significant factors to consider in order to study heat transfer in fluidized-beds. As the first step of investigating the relationship between the interaction of the above factors and the characteristics of heat transfer, an experimental study on the characteristics of pressure fluctuations in fluidized-beds was conducted. It seemed that the high and low frequency of pressure fluctuations appeared beyond the values of Uo/Umf=2. It was found that the frequency of periodic pressure fluctuations depended on the bed height and was not dependent on the superficial gas velocity. These results showed good agreement with Verloop's theoretical results but were higher than Moritomi's experimental results.
