Abstract:

This paper presents the results of two-phase (immiscible liquids) heat transfer studies, conducted using a spiral plate heat exchanger. Experimental studies were conducted using hot water as the service fluid. The two-phase system of nitrobenzene-water in different mass fractions and flow rates was studied as a cold process fluid. The two phase heat transfer coefficients were correlated with Reynolds numbers, Prandtl number, and by the following equation Nu = a. (Re)b. (Pr)c. (X)d, adopting an approach available in the literature for the two-phase flows. The data obtained from the experimental study are compared with the theoretical predictions. The predicted coefficients showed a spread of ± 15 % in the laminar range. This new correlation for predicting Nusselt number may be used for practical applications. © 2010 Bulgarian Academy of Sciences, Union of Chemists in Bulgaria.
