Summary
This investigation attempts to explore the effect of the mechanical behavior of particle-fluid systems on their apparent thermal behavior. Three cases will be studied. The first two will examine the relationship between the particle-pressure and the heat transfer in gas and liquid fluidized beds. (Both gas and liquid fluidized beds will be studied to try and ascertain the effects of bubbling --- which appears in gas-fluidized beds but is generally absent if the continuous phase is a liquid --- on the particle pressure and its effects on the heat transfer.) The last will study the effective thermal conductivity of suspensions as they are sheared in a coaxial cylinder rheometer. This first quarter has been spent largely in design and construction. Of the three apparatuses to be used in this project, only the gas fluidized bed existed at this site prior to this investigation, but even it is being modified to aid the proposed studies. The other two are being built from scratch. In addition, the displacement sensor in the particle pressure transducer for the gas fluidized bed, has been changed from a fiber optic to a capacitance type. Furthermore an analysis has shown that the present design of the particle pressure transducer will not work in the liquid fluidized bed, but the analysis also indicates that a modified design with a porous membrane will solve the problem. 4 figs.
