Modern Methods of Investigation of Heat Transfer Enhancement in Shell-and-Tube Heat Exchangers

Abstract

The article is devoted to the applying of heat supply systems in Russia. It is necessary for creation of comfortable working and recreational conditions. Special attention is paid to the heat-exchange devices which are used for the various types of heat supply systems. It is revealed that shell-and-tube heat exchangers are the most widespread. The emphasis is placed on increase in productivity of such devices by turbulization of liquid at the heat-exchange surface. Basic researches on increase in flow turbulization at the flat firm surface are considered. It leads to the increase in heat emission from the firm surface to the liquid. Application of a program complex for a liquid stream hydrodynamics research is presented.
