Heat Transfer to Vertical Flat Plates in a Rectangular Gas-Fluidized Bed.
Abstract
This experimental study was conducted at the Naval Postgraduate School to investigate the heat transfer characteristics of flat vertical plates in a rectangular gas-fluidized bed. The primary objective was to determine what effect variations in the bed width-to-height ratio had on heat transfer to the vertical flat plates forming the container walls. The experiment was conducted using a specially heated and instrumented fluidized bed equipped with a movable side wall which permitted modification of the bed geometry. As the width of the bed was adjusted, the settled bed height was maintained at a constant level by the addition or removal of bed material. A secondary objective of the study was to determine the effect of variations in the fluidization gas flow rate on heat transfer t the bed walls. Pressure drop measurements as well as visual observations were used to determine minimum fluidization flow rates for each configuration. Heat transfer coefficients were calculated for each flow rate and bed geometry using temperature data obtained from a computer controlled thermocouple network.
