Variable Viscosity Effect on Heat Transfer over a Continuous Moving Surface with Variable Internal Heat Generation in Micropolar Fluids
The effect of temperature-dependent viscosity on heat transfer over a continuous moving surface with variable internal heat generation in micropolar fluids is studied. The fluid viscosity is assumed to vary as inverse linear function of temperature. The governing equations are transformed into dimensionless forms using the stream function and suitable variables then solved numerically using the...
متن کاملVariable Viscosity on Magnetohydrodynamic Fluid Flow and Heat Transfer over an Unsteady Stretching Surface with Hall Effect
The problem of magnetohydrodynamic flow and heat transfer of a viscous, incompressible, and electrically conducting fluid past a semi-infinite unsteady stretching sheet is analyzed numerically. The problem was studied under the effects of Hall currents, variable viscosity, and variable thermal diffusivity. Using a similarity transformation, the governing fundamental equations are approximated b...
متن کاملForced Convection Heat Transfer of Giesekus Viscoelastic Fluid in Concentric Annulus with both Cylinders Rotation
A theoretical solution is presented for the forced convection heat transfer of a viscoelastic fluid obeying the Giesekus constitutive equation in a concentric annulus under steady state, laminar, and purely tangential flow. A relative rotational motion exists between the inner and the outer cylinders, which induces the flow. A constant temperature was set in both cylinders, in this study. The f...
متن کاملViscoelastic Multi-mode Simulations of Wire-coating
A time-stepping nite element method is used to predict the viscoelastic stresses that arise in a tube-tooling wire-coating problem. The polymer melt HDPE is modelled by a multi-mode Phan-Thien/Tanner constitutive equation. Di erent ow geometries are considered to address optimisation of the process with respect to minimising the stress induced within the coating produced. The in uence of the di...
متن کاملViscoelastic Computations of Polymeric Wire-coating Flows
This study considers both a single and multi-mode viscoelastic analysis for wirecoating ows. The numerical simulations utilise a nite element time-stepping technique, a Taylor-Petrov-Galerkin/pressure-correction scheme employing both coupled and decoupled procedures between stress and kinematic elds. An exponential Phan-Thien/Tanner model is used to predict pressure-drop and residual stress for...
