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 non ionic surfactant (oleyldihydroxyetyl amine oxide) as the flow drag reduction additive was dissolved in an organic brine (propylene glycol) 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.
