摘要

Convective heat transfer and pressure drop for dropwise condensation in a compact plate heat exchanger are studied. Experiments using multicomponent mixtures with a relatively high concentration of inert gases are performed. Predictive tools for the Convective heat transfer coefficient, for the pressure drop, and for the composition of the condensate are presented. A prevailing length scale is defined and examined. Measured convective heat transfer coefficients are compared with those obtained in naphthalene mock-up experiments. Mean gas-sided surface-interface temperatures predicted with a new correlation for the heat transfer coefficient are compared with measured ones.
