Computer methods of the analysis of thermo-technical characteristics of heat exchanger-cooler of the “pipe-in-pipe” type

Abstract

In the given work we describe the results of the application of modern computational tools to analyze the thermal performance of the heat exchanger of the “pipe in pipe” type in which in the inner tube refrigerant is circulating – a 50% aqueous solution of propylene glycol, and in the ring backlash – the coolant (water). Thus, on the heat exchange surfaces ofpipes variable (both in time and length) layers of deposits of organic and inorganic origin. This article discusses only the deposits on the surfaces in contact with the coolant.
