Abstract

The flow drag and heat transfer reduction effects of brine flow with drag reduction surfactants have been investigated from the viewpoint of the effective energy consumption in an industrial cooling system. In this study, Oleyldihy-droxyetyl Amine Oxide (ODEAO) of non-ion surfactant was used as a drag reduction surfactant additive, and Ethylene Glycol (EG) was used as a organic brine. It was found that the viscosity of EG brine with ODEAO had the non-Newtonian behavior. The flow friction coefficient and mean forced convection heat transfer coefficient of the EG brine with ODEAO in a straight pipe were measured for each parameter of concentration of EG, concentration of ODEAO and temperature of the brine with ODEAO. The obtained experimental results indicated that the EG brine with ODEAO exerted an influence on the flow drag and heat transfer reduction.
