Abstract
The flow drag and heat transfer reduction effects of brine flow with drag reduction surfactants have been investigated from the effective energy consumption in a pipeline system. In this study, Oleyldihydroxyetyl Amine Oxide (ODEAO) was used as a drag reduction surfactant additive, and Ethylene Glycol (EG) solution was selected as the brine. The pipe friction coefficient and mean heat transfer coefficient of the EG solution flow with ODEAO were measured as parameters of EG concentration, solution temperature and ODEAO concentration. The obtained experimental results indicated that the EG concentration exerted an influence on the flow drag and heat transfer reduction characteristics of the EG solution flow with ODEAO.
