Overall Heat Transfer Coefficients for a Horizontal Cylinder in a Fluidized Bed.

Abstract

Total heat transfer coefficients were determined for a heated, copper cylinder placed horizontally in a fluidized bed. The fluidized particles were glass beads ranging in size from 215 micrometers to 3.40 mm. Fluidization was accomplished using air. Temperatures were measured using thermocouples and the resulting h values tabulated and plotted as a function of superficial velocity and relative velocity. Nusselt numbers based on particle diameter and tube wall diameter were also determined. The results show consistent patterns with other workers and are substantiated by empirical correlations.
