IMPACT OF CHANGE IN INLET TEMPERATURE OF HEATED FLUID ON TERMIC CHARACTERISTICS OF OPPOSITE DIRECTIONAL HEAT EXCHANGER "BEAN OF PIPES IN A SHELL"

Abstract

Although the most simple type and despite the fact there are more efficient heat exchangers, those of the type "pipe and a shell" are used often. The goal of this paper is to show how the change in temperature in heat fluid at the entrance into the heat exchanger affects its thermal characteristics. The object of research is the opposite stream heat exchanger "flux of pipes in the shell". The role of working fluid on the side of the primary has water, as on the side of the secondary. Research is conducted numerically and commercial software ANSYS Workbench 15.0 was used.
