Transient Electro-osmotic Slip Flow of an Oldroyd-B Fluid with Time-fractional Caputo-Fabrizio Derivative
In this article, the electro-osmotic flow of Oldroyd-B fluid in a circular micro-channel with slip boundary condition is considered. The corresponding fractional system is represented by using a newly defined time-fractional Caputo-Fabrizio derivative without singular kernel. Closed form solutions for the velocity field are acquired by means of Laplace and finite Hankel transforms. Additionally...
متن کاملA note on an unsteady flow of an Oldroyd-B fluid
The laminar flow of a number of fluids such as polymeric liquids, food products, paints, slurries, foams, and so forth cannot be adequately described by the help of the classical linearly viscous Newtonian model. Thus, there is a need to have at hand an arsenal of non-Newtonian fluid models and over the past several decades a variety of models have been developed. While the fluids of the differ...
متن کاملA note on the flow induced by a constantly accelerating edge in an Oldroyd-B fluid
Analytical expressions for the velocity field and the tangential stresses that are induced due to a constantly accelerating edge in an Oldroyd-B fluid have been established for all values of material constants. The solutions that have been obtained satisfy the governing differential equations and all the imposed initial and boundary conditions. These solutions reduce to those for the Maxwell, s...
متن کاملFlow of an Oldroyd-fluid in a contracting channel with a moving boundary
The industrial process of coating flat surfaces with polymeric substances is numerically simulated by solving the full equations of motion for a flow through a contraction with a moving boundary. The four-constant Oldroyd constitutive equation is used to represent the viscoelastic fluid. Some adjustments to existing finite-difference methods are made in such a way as to avoid singular iterative...
متن کاملA Numerical Study on Wire Coating Analysis in MHD Flow of an Oldroyd 8-Constant Fluid
Wire coating process is an industrial process to coat a wire for insulation, mechanical strength and environmental safety. The ever increasing applications in the industrial process are the cause of great interest in the study of viscoelastic flow in the wire coating process in a pressure type die. In the present study we provide a numerical solution of the Navier-Stokes equation for wire coati...
