Constant 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...
متن کاملMathematical modelling of Sisko fluid flow through a stenosed artery
In the present study, the nonlinear model of non-Newtonian blood flow in cosine-shape stenosed elastic artery is numerically examined. The model is carried out for axisymmetric, two-dimensional and fully developed blood flow. The vessel wall is assumed to be have time-dependent radius that is important factor for study of blood flow. The cosine-shape stenosis convert to rigid artery by using a ...
