In this study, we investigated the temperature dependent viscosity effect on magnetohydrodynamic nanofluid flow caused by a heated/cooled cone in the presence of nonlinear thermal radiation and irregular heat source/sink. The transformed governing equations using similarity variables are solved numerically using Runge-Kutta based shooting technique. We demonstrated solutions for Al2O3-water and TiO2-water nanofluid cases. The effects of various dimensionless parameters on velocity and temperature profiles along with the skin friction coefficient and the local Nusselt number are discussed and presented with the help of graphs and tables. It is found that the viscous variation parameter help to control the velocity as well as the temperature field and regulates the friction factor and heat transfer rate.
