Heat transfer research of additive drag reduction in heating system

This paper mainly studied the change of heat transfer coefficient of different radiators in heating system at various temperatures respectively with water and the additives cetyltrimethyl ammonium chloride CTAC, and the change of pressure loss of radiator in the local system with flow. The conclusion was drawn from the experiment data that heat transfer coefficient increases with 20ppmCTAC additives added in the heating network system, and the pressure loss of local system decreases.
