Numerical solution of mixed convection flow of an MHD Jeffery fluid over an exponentially stretching sheet in the presence of thermal radiation and chemical reaction
We numerically investigate a mixed convection model for a magnetohydrodynamic (MHD) Jeffery fluid flowing over an exponentially stretching sheet. The influence of thermal radiation and chemical reaction is also considered in this study. The governing non-linear coupled partial differential equations are reduced to a set of coupled non-linear ordinary differential equations by using similarity functions. This new set of ordinary differential equations are solved numerically using the Spectral Quasi-Linearization Method. A parametric study of physical parameters involved in this study is carried out and displayed in tabular and graphical forms. It is observed that the velocity is enhanced with increasing values of the Deborah number, buoyancy and thermal radiation parameters. Furthermore, the temperature and species concentration are decreasing functions of the Deborah number. The skin friction coefficient increases with increasing values of the magnetic parameter and relaxation time. Heat and mass transfer rates increase with increasing values of the Deborah number and buoyancy parameters
Numerical solution of mixed convection flow of an MHD Jeffery fluid over an exponentially stretching sheet in the presence of thermal radiation and chemical reaction
We numerically investigate a mixed convection
model for a magnetohydrodynamic (MHD) Jeffery fluid
flowing over an exponentially stretching sheet. The influence
of thermal radiation and chemical reaction is also
considered in this study. The governing non-linear coupled
partial differential equations are reduced to a set of
coupled non-linear ordinary differential equations by using
similarity functions. This new set of ordinary differential
equations are solved numerically using the Spectral
Quasi-Linearization Method. A parametric study of physical
parameters involved in this study is carried out and
displayed in tabular and graphical forms. It is observed
that the velocity is enhanced with increasing values of the
Deborah number, buoyancy and thermal radiation parameters.
Furthermore, the temperature and species concentration
are decreasing functions of the Deborah number.
The skin friction coefficient increases with increasing values
of the magnetic parameter and relaxation time. Heat
and mass transfer rates increase with increasing values of
the Deborah number and buoyancy parameters
A Note on Improved Homotopy Analysis Method for Solving the Jeffery-Hamel Flow
This paper presents the solution of the nonlinear equation that governs the flow of a viscous, incompressible fluid between two converging-diverging rigid walls using an improved homotopy
analysis method. The results obtained by this new technique show that the improved homotopy
analysis method converges much faster than both the homotopy analysis method and the optimal
homotopy asymptotic method. This improved technique is observed to be much more accurate
than these traditional homotopy methods
