In a confined simple shear flow, the macromolecules of polymeric liquid reorient near walls so that measured viscosity decreases. For instance, in small-amplitude oscillatory real part complex decreases with confinement, and macromolecular orientation explains this. These effects oscillation have been explained analytically for rigid dumbbell suspension and, summation coefficients determined. B...

secondary flow investigation could be regarded as an important issue in open channel flow, in spite of its lower quantity compared to the base flow in the water course. it should be given special consideration because of the influence on some hydraulic factors in open channel, specifically in compound channels. in compound channels' due to the difference in the flow velocity of the main ch...

This short note presents a derivation of the velocity description of deformation for the geometric models of pure-shear and simple-shear faultbend folding. This allows the calculation of rates of displacement, uplift and limb-rotation associated with such structures and their comparison with classical fault-bend folds. Using this velocity description, we examine the differences between pure-she...
