Experimental and Rheological Investigation on the Effect of SBR1502 Copolymer on Transportation of Oil through Horizontal Pipe

Turbulent flows can occur in the boundary layer near solid surfaces and the associated friction increases, as the flow velocity increases. The energy losses and self-noise due toturbulence friction can be of very high magnitude. This necessitates unabated research into drag reduction. Dragreduction phenomenon is a drastic decrease in friction drags and pressure drop with the addition of little quantity of additives about few ppms.Toms [1] was the first to publish drag reduction data whichwas later named as the Toms effect. In the last sixty years, many theoretical, experimental and simulation computingstudies, have been done on the effect of dilute polymer solutions on drag reduction, because of its useful applications ,and significant role in gaining knowledge on turbulent flows. The objective of this study was to find the effect of Styrene- Butadiene-Rubber 1502 (SBR1502) copolymer as a new drag reducer agent (DRA) on turbulent flow of Gachsaran crude oil in horizontal pipe. We examined the polymer solutions atdifferent concentrations of the SBR1502 to find the optimum concentration and optimum velocity for drag reduction. In thisstudy, we also focused on the rheological behavior of this polymer solution system
