摘要

In this paper, we present experimentally the influence of the main geometric and thermo-physical properties on the performances of industrial heat exchangers, functioning in wet regime by partial or total condensation of the water vapor contained in the humid air over the smooth or finned tubes-heat exchangers. Three heat exchangers are considered here: 1-smooth tubes and staggered bundle, 2-finned-tubes and staggered bundle, and 3-finned-tubes and aligned bundle. We aim by the different tests for each geometry to get laws of heat transfer and pressure loss, as well as the heat fluxes and condensate water vapor flowrates. The humid air temperature varies between 100℃ and 350℃.
