Viscoelastic Merging Flow in a T-Shaped Tube

Spatially Varied Flow Profiles in a V-Shaped Side-Channel

Resistance to Flow in a V-Shaped Bottom Channel

Water flow in open channels is always subject to the resistance to flow and energy dissipation. For design purposes, one of the needed variables is the hydraulic resistance coefficient. For this mean, the influence of cross-sectional shape together with secondary flow cells and lateral distribution of true boundary shear stress have not yet been fully explored. This paper surveys the number of ...

Peristaltic Viscoelastic Fluid Motion in a Tube

Peristaltic motion of viscoelastic incompressible fluid in an axisymmetric tube with a sinusoidal wave is studied theoretically in the case that the radius of the tube is small relative to the wavelength. Oldroyd flow has been considered in this study and the problem is formulated and analyzed using a perturbation expansion in terms of the variation of the wave number. This analysis can model t...

Embedded Recovery Methods for Viscoelastic Flow past a Sphere in a Cylindrical Tube

The motivation for this study is to capture the superior accuracy properties of recovery methods and their application to the numerical solution of nonlinear viscoelastic ows. For velocity gradient recovery, local direct methods are compared to Galerkin least squares methods. Superconvergence properties are intrinsic. We compare and contrast averaging and patch recovery approaches. We investiga...

Flow Visualization Around a Non - Circular Tube

The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...
