Apparent Slip for an Upper Convected Maxwell Fluid
In this study the flow field of a nonlocal, diffusive upper convected Maxwell (UCM) fluid with a polymer in 3 a solvent undergoing shearing motion is investigated for pressure driven planar channel flow and the free boundary problem 4 of a liquid layer on a solid substrate. For large ratios of the zero shear polymer viscosity to the solvent viscosity, it is shown 5 that channel flows exhibit bo...
متن کاملAnalysis of Fiber Spinning for the Upper-convected Maxwell Fluid
The fiber spinning process of a viscoelastic liquid modeled by the constitutive theory of the Maxwell fluid is analyzed. The governing equations are given by one-dimensional mass, momentum and constitutive equations which arise in the slender body approximation by cross-sectional averaging of the two-dimensional axisymmetric Stokes equations with free boundary. Existence, uniqueness and regular...
متن کاملUniaxial Compression of a Hard Wheat Flour Dough: Data Analysis Using the Upper Convected Maxwell Model
T7ze behavior of a hard wheat flour dough has been measured in lubricated uniCLrial compression experiments at compressional rates (crosshead speeds) of 0.2, 2 and 20 em/min. T7ze appropriate differential equation, derived for an upper convected MCLnvell model, while taking into account the changing strain rate during the compression at constant crosshead speed, was solved numerically. With a s...
متن کاملSymmetry Analysis of Boundary Layer Equations of an Upper Convected Maxwell Fluid with Magnetohydrodynamic Flow
Steady state boundary layer equations of an upper convected Maxwell fluid with magnetohydrodynamic (MHD) flow are considered. The strength of the magnetic field is assumed to be variable with respect to the location. Using Lie group theory, group classification of the equations with respect to the variable magnetic field is performed. General boundary conditions including stretching sheet and i...
