Abstract
Analysis is performed to investigate the effects of thermal radiation and non-uniform heat generation/
absorption on free convection boundary layer over a non-isothermal vertical permeable cone
in a non-Newtonian power-law fluid saturated porous medium. The governing equations describing
the problem are transformed into nonlinear ordinary differential equations using similarity transformation,
which are solved numerically. Numerical computations are carried for various values of the
parameters on the dimensionless temperature as well as the local Nusselt number. The results
show that the thermal radiation parameter, the absolute value of the suction parameter and the
heat generation parameter have the effect of depressing the local Nusselt number, whereas the
power-law index parameter, the surface temperature exponent parameter, the injection parameter
and the heat absorption parameter have the effect of enhancing the local Nusselt number.
