    Effect of surfactant/counter ion ratio on durability and drag reduction effectiveness of micellar solutions

  • Original language description

    The age of micellar solution influences substantially effectiveness of drag reduction in a turbulent flow in tubes. In this contribution are shown effects of both surfactant concentration and the ratio of the surfactant to the compound containing conterion, and their role in degradation rate at aging.Experiments were made with different concentrations of cationic surfactant CTAB (Hexadecyltrimethyl ammonium bromide) in mixture with NaSal (Sodium salycilate).

    Vliv poměru složek micelárních aditiv na trvanlivost roztoku a schopnost snižovat tření

  • Czech description

    Stáří micelárních roztoků podstatně ovlivňuje schopnost snižovat tření při turbulentním proudění v trubkách. Byl studován jednak vliv kocentrace surfaktantu a jednak vliv poměru surfaktantu a přísady upravující iontovou sílu roztoku na stupeň degradace při stárnutí micelárního roztoku. Experimenty byly provedeny s různými koncentracemi kationaktivního surfaktantu CTAB (hexadecyltrimethylamonium bromid)ve směsi s NaSal (salycilan sodný).
