The effect of acoustic field on the heat transfer coefficient for binary component system has been studied in a 150 mm I. D. column of fluidized bed. In this paper mixing characteristics of two kinds of particles having different sizes and densities, and the heat transfer coefficient within them were experimentally examined using immersed horizontal heating tube in the gas-solid fluidized bed. The experimental result showed that the heat transfer coefficient for binary system increases with increase in sound pressure level, also, the minimum fluidization velocity for binary system decreased with the increase in sound pressure level. Better particle mixing can be obtained by combined effect of acoustic field and the fluidizing velocity.

Abstract


The effect of acoustic field on the heat transfer coefficient for binary component system has been studied in a 150 mm I. D. column of fluidized bed. In this paper mixing characteristics of two kinds of particles having different sizes and densities, and the heat transfer coefficient within them were experimentally examined using immersed horizontal heating tube in the gas-solid fluidized bed. The experimental result showed that the heat transfer coefficient for binary system increases with increase in sound pressure level, also, the minimum fluidization velocity for binary system decreased with the increase in sound pressure level. Better particle mixing can be obtained by combined effect of acoustic field and the fluidizing velocity.
