On Thermal Radiation Effect in the MHD Jeffery-Hamel Flow of a Second Grade Fluid
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 7
Abstract
This paper explores the thermal radiation effect in the two-dimensional and magnetohydrodynamic (MHD) flow of an incompressible non-Newtonian fluid in a convergent/divergent channel. The fluid is considered to be thermodynamically second grade. The mathematical formulation involves the conservation of laws of mass, linear momentum and energy with Rosseland’s approximation. The resulting nonlinear analysis is computed with the implementation of differential transformation method (DTM). Solutions for velocity and temperature are derived. Computations for the skin friction coefficient and local Nusselt number are also established. Both cases of convergent and divergent channel are analyzed. Comparison of present results with the previous relevant approximate and numerical solutions is shown. It is observed that the temperature is decreasing function of thermal radiation.
