Heat Transfer Between Gas and Liquid in a Bubble Column
Original language description
Multiphase contactors, e.g. bubble columns, are often used in operations accompanied by heat transfer between the phases. Literature studies have divided heat transfer measurements in two- and three-phase systems into: (i) estimations of bed-to-wall heat transfer coefficients, and (ii) estimations of immersed object-to-bed heat transfer coefficients. Although wall-to-bed and heat-exchange element-to-bed heat transfer coefficients have been intensively studied and published, no correlations have been found for gas-to-liquid heat transfer for bubble columns. The aim of this paper is to determine the effect of multi-orifice aerator for the heat transfer between gas and liquid and to compare two different aerator patterns. This study was performed on the bubble column 0.15 m in diameter with various water levels within the range of superficial gas velocity varying from 0.01 m s-1 to 0.1 m s-1. The gas-to-liquid heat transfer measurements were performed by a non-steady state method based on measurements of the gas- and liquid- temperature in the time for an evaluation of the heat fluxes and heat transfer coefficients.
