There has been some interest in the flow drag and heat transfer reduction effects of brine flow with drag reduction surfactants in order to achieve the effective energy consumption in an industrial cooling system. Therefore, there have been our previous investigations of brine flow (Ethylene Glycol (EG) solution for organic brine) with drag reduction surfactant (Oleyldihydroxyetyl Amine Oxide (ODEAO) of non-ion surfactant) showing the flow drag and heat transfer reduction effect. But some technical issues are that EG is an environmentally harmful brine and the use of EG will be restricted in the future. Whereas, Propylene Glycol (PG) and Potassium Acetate (=PA) are expected to be environmentally friendly brines. But, there have been few studies on the flow drag and heat transfer reduction effects of PG or PA solution with drag reduction surfactants. This present paper shows that the flow friction coefficient and mean forced convection heat transfer coefficient of the PG, or PA solution with ODEAO in a straight pipe were measured for each parameter of concentration of brines, concentration of ODEAO and temperature of the brine with ODEAO. Finally, useful non-dimensional correlative equations for maximum flow resistance and heat transfer reduction effect are derived in terms of various non-dimensional parameters, and these experimental results of PG solution with ODEAO were compared with that of EG solution with ODEAO.
