The Simulation of Multicomponent Mixtures Condensation in Plate Condensers

- Introduction

“…The increase of static pressure due to deceleration can be calculated as difference between dynamic pressures at outlet and inlet of the channel or part of its length: Here, G is mass velocity (or flux) of two-phase flow in the channel, kg/(m 2 · s). According to Tovazhnyansky et al (2004), for the small increment of the channel length, it can be approximately estimated using vapour velocity calculated for all cross-sectional area: Lockhart and Martinelly (1949) came to the same conclusion with note that its significance increases at low-pressure vapour condensation.…”

The use of plate heat exchangers to improve energy efficiency in phosphoric acid production

“…The calculation algorithms were developed on the basis of research results for heat and mass transfer in PHE channels reported earlier in papers by Tovazshnyansky et al [28][29][30], with the use of coefficients in correlation with heat transfer and with hydraulic resistance obtained for single phase flow in the same inter plate channel, as described earlier in this paper.…”

Heat transfer—A review of 2004 literature

“…Marangoni effects in condensation heat transfer were studied for water/ethanol , ammonia/steam [JJ49,JJ50], zeotropes [JJ51], mixtures of vapors of immiscible liquids [JJ52] and other multi-component mixtures [JJ53] and in shell-and-tube condensers [JJ54,JJ55].…”
