FLOW RESISTANCE AND HEAT TRANSFER CHARACTERISTICS OF ORGANIC BRINE (PROPYLENE GLYCOL) SOLUTION BY ADDING FLOW DRAG REDUCTION ADDITIVE
The flow drag and heat transfer reduction effect of brine solution is important technology for the effective energy consumption system. A nonionic surfactant (oleyldihydroxyetyl amine oxide) as the flow drag reduction additive was dissolved in an organic brine (propyleneglycol) solution. The pipe friction and heat transfer coefficients of this brine solution have been measured for some experimental parameters. It was found that the flow resistance and heat transfer coefficients of this solution were decreased in the turbulent flow range, but the flow drag and heat transfer reduction tendency was varied with different ranges of the solution temperature.
