Зміна гідромеханічних і теплофізичних характеристик теплоносія в приграничному шарі під дією поверхнево-активних речовин (ПАР)

Abstract

The acticle deals with the change of hydromechanical and heating physical characteristics of heat-carrying agent, that move in tube of apparatus, namely, in by-limiting layer under the action of anionic surfactants. It was found out experimentally the optimal concentrations steam, which are investigated in water, the coefficient of surface tension was minimal. It was also shown that a reduce of surface tension coefficient minimize a thickness of by- limiting L layer in system of pipeline – water wall, it means that it increase an average speed of stream in this L layer. Numerical range of surface criterion for water solution surfactants. Were found out and are investigating. Minimal meaning of surface criterion are observed at optimal concentrations surfactants.
