Abstract Drag reduction (DR) by the additive of mixed surfactant and polymer is investigated in detail in a rotating disk apparatus (RDA). Polyethylene oxide
(PEO) and Cetyltrimethyl ammonium chloride (CTAC)/sodium salicylate (NaSal) are chosen as polymer and surfactant, respectively. It is investigated
on the influence of combination concentration of polymer & surfactant, temperature and Reynolds number on the drag-reducing rate. The present
experimental results show that the drag-reducing rate of the mixed solution is definitely higher than that of the pure PEO or CTAC/NaSal solutions.
This phenomenon is especially sharp at the high temperature and/or the… More >
