Dynamics of worm-like micelles: the Cox–Merz rule

Nonlinear shear and extensional flow dynamics of wormlike surfactant solutions

“…The solid lines in Figure 5 Small deviations of the solution viscosity at high shear rates from the expected complex viscosity (Eq. (9)) of the Rouse-like regime have also been reported by Manero et al [14].…”

“…A cationic surfactant EHAC (erucyl bis (2-hydroxyethyl) methyl amomonium chloride) has very recently been used in several studies with different counterions (EHAC/NaSal/Water, EHAC/NaCl/Water, and EHAC/NaTos/Water [11][12][13]; EHAC/2-propanol/KCl/Water [14], EHAC/KCl/Water [15]). Raghavan and Kaler [11] have reported that EHAC-based solutions can form an entangled network of extremely long wormlike micellar chains and are highly viscoelastic or gel-like with increasing salt concentration.…”

PET-MMT and PET-PEN-MMT Nanocomposites by Melt Extrusion

“…An example of a constitutive equation which describes these processes is the BMP equation of state. This equation [Bautista et al 1999;Manero et al 2002] is written here in terms of a stress superposition according to: are scalars that reflect changes in viscosity due to changes in the structure induced by flow. β i =k i λ i can be interpreted as an inverse of the energy associated to www.intechopen.com…”

Numerical Analysis of Shear Banding Flow of Wormlike Micelle Solutions between Parallel Channels using a Network Scission Model

“…In numerical studies, flow analyses for wormlike micelle solutions using continuum constitutive equations, such as the diffusive Johnson-Segalman model [13][14][15][16][17] , the Giesekus model [18][19][20] , and Bautista-Manero models [21][22][23][24][25] were performed. In continuum constitutive equations, the behavior of microscopic or mesoscopic network structures of micelles are not explicitly described.…”
