Abstract: | <p>An experimental investigation of an Atomized Suspension Technique system was carried out in an experimental apparatus of semi-pilot plant scale. The complex gas flow patterns which occur in such systems as the result of the interaction of natural convection and forced convection prevented a quantitative analysis of the system.</p> <p>The problem was then approached by dividing the overall process into a number of idealized studies; these were convection in the entrance region, radiation to a gas, radiation to a cloud of droplets.</p> <p>A theoretical model was developed to predict heat-transfer rates and gas temperature profiles in the entrance region (x/D < 2) of a cylindrical coolumn. The model was verified experimentally.</p> <p>A theoretical gas- radiation model was developed using the zoning technique of Hottel. Experimental gas-temperature measurerrents qualitatively verified the model.</p> <p>An investigation of the established immersion cell technique for the determination of drop-size distributions in sprays indicated that this technique could not be used with any confidence in systems where the spray is moving at low velocities.</p> <p>Several experimental devices and techniques were developed throughout the course of this study.</p> |
