The investigation of vapor condensation in horizontally oriented channels with cross corrugated walls

Abstract

The problem of heat transfer for flows in channels of plate heat exchangers with cross corrugated walls is very complicated, especially relating to two phase flows. The subject of the investigation is the process of vapor condensation in horizontally oriented channels formed by corrugated plates. The corrugation of plates is complicated and consists of different patterns. The experimental investigations were carried out for single phase flow in channels under investigation and for condensation of pure vapor and vapor containing non condensable gases. Appropriate relationships were obtained. The results of investigation were used for development of special plate heat exchanger for condensation column of ammonia synthesis unit, where the condensation of synthetic ammonia occurs. The manufactured plate unit was installed into existing condensation column. The results of industrial tests are in good agreement with experimentally based relationships used for calculations and design of the plate heat exchanger.
