The process of steam condensation in the presence of non-condensing air inside channels of Plate Heat Exchanger (PHE) is investigated based on experimental data and the results of mathematical modelling. The model consists of a system of ordinary differential equations with nonlinear right parts, solved numerically on a computer. It describes the local process parameters distribution in channel. Each of the PHE tested samples consists of four corrugated plates with three channels between them for the flow of hot and cold streams. The experimental samples have different angles of corrugations to the longitudinal plate axis (60 degrees, 45 degrees and 30 degrees). The applicability of heat-momentum and heat-mass transport analogies for such channels was confirmed, as also the preservation of the Equation for the correction on effect of transverse mass flux in criss-cross flow channels. The specific form of such Equation is proposed. It allows mathematical modelling of steam-air mixture condensation using single-phase correlations for PHE channels. The intensification of overall heat transfer compared to condensation in flat wall channels is observed. It enables the decrease of PHE heat transfer area from 2 up to 4 times compared to a flat wall channel for the same process conditions.
