Direct Contact Condensation of Immiscible Fluids in Packed Beds

摘要

An experimental study of a film type direct contact heat exchanger using immiscible fluids is made. Laboratory experiments were conducted on a R-113-water system using both 2.5 cm Berl saddles and 3.2 cm spheres as packing, in a 14.6 cm diameter column. The configuration was counter flow, with the vapor phase entering at the base of the column, and condensing on the laminar water film that coated the packing surface. Packing height, water temperature and both water and vapor flow rates were varied in obtaining heat transfer data. These and other packed bed heat transfer data published in the literature were reduced and correlated to yield a relationship between the Stanton number and the important vessel operating parameters.
