Predicting of Temperature Distribution in Direct Contact Heat Transfer

Abstract

An experimental and theoretical investigation of three phase direct contact heal transfer by evaporal ion of refrigerant drops in an immiscible liquid has been carried out Refrigerant R/2 and R134a were usedfor the dispersed phase, while water and brine were the immiscible continuous phase. A numerical analysis is presented to predict the temperature distribution throughout the circular test column radially and axially is achieved. Experimental measurements of the temperature distribution have been compared with the numerical results and are discussed .A comparison between the crperimental and theoretical results showed acceptable agreement and applicability of the derived equations. Comparison with other related work showed similar behavior.
