The paper presents the analysis of the possibilities of intensification of drag reduction effect (DR) by simultaneous addition of non-ionic high molecular polymer - poly(ethylene oxide) and the cationic surfactant - cetyltrimetyl ammonium bromide into the solvent. Salt sodium salicylate was applied as a counter-ion. The analyzed solutions were compared with their pure polymer or micellar equivalents. Clear existence of three drag reduction zones was observed: stable transitional zone, unstable transitional zone and in particular the third turbulent drag reduction zone. The dominant factor which influenced DR in the transitional zone was the addition of CTAB + NaSal. In the third zone, the addition of PEO had decisive influence on the DR intensity. The increase of PEO concentration enhanced DR in this zone. The influence of pipes diameter on the DR was investigated. The increase of pipe diameter caused clear extension of the stable transitional zone. In the third zone DR increased while decreasing pipe diameter. Analyses showed that the value of the n flow index was not an important factor in the DR. The results indicate that polymer-micellar solutions combine and intensify positive features of their pure polymer and micellar equivalents, providing efficient DR in a wider range of the Reynolds numbers.
