Available in PDF, EPUB and Kindle. Book excerpt: "In this thesis, we examine the numerical simulation of transient viscoelastic flows with two moving free surfaces. A modified Galerkin finite element method is implemented to the two-dimensional non-steady motion of a viscoelastic fluid. The fluid is initially placed between two parallel plates and bounded by two straight free boundaries. In this Lagrangian finite element method, the spatial mesh deforms in time along with the moving free boundaries. The unknown shape of free surfaces is determined with the flow field u, v, $ tau$, p by the deformable finite element method, combined with a predictor-corrector scheme in an uncoupled fashion. In this study, the moving free surfaces and fluid motion of both Newtonian and non-Newtonian flows are investigated. The results include the influence of the time increment and the finite element mesh size, the effects of surface tension, fluid inertia and elasticity." --

Available in PDF, EPUB and Kindle. Book excerpt: This monograph is based on a series of lectures presented at the 1999 NSF-CBMS Regional Research Conference on Mathematical Analysis of Viscoelastic Flows. It begins with an introduction to phenomena observed in viscoelastic flows, the formulation of mathematical equations to model such flows, and the behavior of various models in simple flows. It also discusses the asymptotics of the high Weissenberg limit, the analysis of flow instabilities, the equations of viscoelastic flows, jets and filaments and their breakup, as well as several other topics.

This book was released on 2006 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: (cont.) Two different decoupled methods for computing the velocity gradient, one using a global least squares approximation and the other a local patch algorithm, are explored. While both methods reduce to the true velocity gradient with mesh refinement, the patch algorithm is shown to require significantly more mesh refinement than the global least squares approximation to order to attain equivalent refinement of the solution. Comparison of the two methods taking into account the additional refinement requirements of the local patch algorithm makes clear the superiority of the decoupled global least squares approximation for calculation of the velocity gradient interpolant. The versatility and robustness of the decoupled form of the DEVSS-G equations are demonstrated through the addition and modification of the evolution equations describing the stress of the polymer as well as new physical quantities of the flow. A time-dependent, free-surface finite element method is developed in which an evolution equation derived from the kinematic boundary condition is used to describe the height of the free surface as a function of time.

Download or read book Walters B Viscoelastic Flow Past a Vertical Plate written by V. Ramachandra Prasad and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive analysis of Walters-B Viscoelastic flow past a vertical plate. Owing to the significance of this problem in chemical and medical biotechnological processing (e.g. medical cream manufacture) we study the transient case of such a flow in the present paper using the robust Walters-B viscoelastic rheological material model. A Crank-Nicolson finite difference scheme is utilized to solve the unsteady dimensionless, transformed velocity, thermal and concentration boundary layer equations in the vicinity of the vertical plate and the results are discussed in detail. It helps researchers, students, engineers and scientists who work in the area of non-Newtonian fluid flows.

Available in PDF, EPUB and Kindle. Book excerpt: Non-Newtonian (non-linear) fluids are common in nature, for example, in mud and honey, but also in many chemical, biological, food, pharmaceutical, and personal care processing industries. This Special Issue of Fluids is dedicated to the recent advances in the mathematical and physical modeling of non-linear fluids with industrial applications, especially those concerned with CFD studies. These fluids include traditional non-Newtonian fluid models, electro- or magneto-rheological fluids, granular materials, slurries, drilling fluids, polymers, blood and other biofluids, mixtures of fluids and particles, etc.
