A surfactant, cetyltrimethylammonium bromide (CTAB) forms wormlike micelles in aqueous solutions with additive of sodium salicylate (NaSal). Wormlike micelles can self-organize under flow to form higher-order flow-induced structures (FISs). In thi...
A catiomc surfactant,cetyltrimethylammonium bromide,CTAB,forms wormlike micells in aqueous solution with sodium salicylate,NaSal.Wormlike micelle solutions have viscoelastic characteristics originated from network of micells.Aqueous solutions of C...

Axisymmetric flow of surfactant solutions past a sphere moving at constant velocity is experimentally investigated. Test fluids used are entangled wormlike micelle solutions of 30mM cetyletrimethylammonium bromide and sodium salicylate at various ...
A cationic surfactant, cetyltrimethylammonium bromide, CTAB, forms wormlike micelles in aqueous solution with sodium salicylate, NaSal Aqueous surfactant solutions which form wormlike micelles have viscoelastic characteristics originated from netw...
In the present study, flow structure behind a sphere falling through aqueous solutions of CTAB/NaSal are examined using a dye visualization and a PIV. Visualized dye patterns indicate that aqueous solutions of CTAB/NaSal forms multi layered struct...
