Summary
A heat transfer analysis of a liquid-liquid spray column operating as a direct-contact heat exchanger is presented. The analysis is based upon an iterative procedure originally proposed by Bühler. A major modification of the previously used analytical procedures is based on the assumption of free convection heat transfer inside the drops rather than of forced convection. Predicted heat transfer coefficients and heat transfer rates are compared with experimentally obtained data. A sensitivity analysis is used to demonstrate the degree of dependence of the analytical results on input parameters.
