RESISTANCE OF FRICTION AND HEAT TRANSFER IN TURBULENT FLOWS OF AQUEOUS SOLUTIONS OF HYDRODYNAMICALLY ACTIVE POLYMERS AND SURFACE-ACTIVE SUBSTANCES
The reduction of hydrodynamic resistance of turbulent friction (HRTF) of liquids with the addition of high molecular-mass polymers (HMP) and micelle-forming surfactants (MSAS) has prospects for wide practical application. In addition, the study of the physical nature of the effect of reducing HRTF leads to a better understanding of the basic laws of near-wall turbulent flows. In the present article, based on the available publications, the main regularities of the influence of hydrodynamically active additives on friction resistance and heat transfer in turbulent fluid flows are systematized and recommendations on hydrodynamic design of heat exchangers for centralized heat and cold supply systems are developed.
