Abstract
The study reported here is concerned with mathematical modeling of nonisothermal mass transfer by means of countercurrent direct contact of immiscible liquids in spray towers. Heat and mass transfer performance of spray tower heat exchangers were measured by United States government contractors at pilot plant scale over several operating parameters.
The results of the study indicate that wake phenomena control the amount of heat and mass transfer in spray towers. A useful numerical algorithm is developed and presented to explain the observed phenomena.
Results of an extensive parameter study which includes flow rates, dissolved solids, drop diameter, and entrance temperatures for respective phases, are discussed.
