Steady flow and heat transfer analysis of Phan-Thein-Tanner fluid in double-layer optical fiber coating analysis with Slip Conditions
Modern optical fibers require double-layer coating on the glass fiber to provide protection from signal attenuation and mechanical damage. The most important plastic resins used in wires and optical fibers are plastic polyvinyl chloride (PVC) and low-high density polyethylene (LDPE/HDPE), nylon and Polysulfone. In this paper, double-layer optical fiber coating is performed using melt polymer sa...
متن کاملDouble-layer Optical Fiber Coating Analysis by Withdrawal from a Bath of Oldroyd 8-constant Fluid
In the present work we explore an approximate solution of the Navier-Stokes equations for optical fiber coating in a pressure type die by withdrawal from a bath of two immiscible Oldroyd 8-conatant fluid under constant pressure gradient in the axial direction using two-layer coating flow. The constitutive equation of motion has been solved by using optimal homotopy asymptotic method (OHAM) for ...
متن کاملConstant Wall Temperature Forced Convection in Pipes with the Simplified Phan-thien—tanner Fluid
The fully-developed thermal and hydrodynamic steady laminar pipe flow of the SPTT fluid is here investigated for the constant wall temperature boundary condition, assuming constant properties and negligible axial conduction. Two limiting conditions were identified: the solution pertaining to the equilibrium between axial convection and radial conduction of thermal energy, and the solution of th...
متن کاملInvestigation of blood flow rheology using second-grade viscoelastic model (Phan-Thien-Tanner) within carotid artery.
PURPOSE Hemodynamic factors, such as Wall Shear Stress (WSS), play a substantial role in arterial diseases. In the larger arteries, such as the carotid artery, interaction between the vessel wall and blood flow affects the distribution of hemodynamic factors. The fluid is considered to be non-Newtonian, whose flow is governed by the equation of a second-grade viscoelastic fluid and the effects ...
متن کاملFrom the Phan-Thien Tanner / Oldroyd-B non-Newtonian model to the double shear thining Rabinowisch thin film model
In this paper, an asymptotic expansion is used to derive a description of Phan-Tien Tanner / Oldroyd-B flows in the thin film situation without the classical “Upper Convective Maxwell” assumption. We begin with a short presentation of the Phan-Thien Tanner / Oldroyd-B models which introduce viscoelastic effects in a solute-solvant mixture. The three dimensional flow is described using five para...
