Abstract
The effects of temperature dependent viscosity and thermal conductivity of a micropolar fluid over a continuous moving stretching surface with radiation is examined. The micropolar model due to Eringen is used to describe the working fluid. The partial differentia equations governing problem under consideration have been transformed into a system of non linear differential equations by the similarity transformations and then solved numerically using shooting technique. Numerical results are carried out for various dimensionless parameters of the problem especially variable viscosity parameter, thermal conductivity parameter, micro-rotation parameter along with the Prandtl number. The results are presented graphically for velocity distribution, temperature distribution and micropolar
distributions for various values of non-dimensional parameters. It is found that the effects of the parameters representing variable property of viscosity and thermal conductivity aresignificant
