This work studies the free convection heat transfer from a non-isothermal permeable cone with suction and temperature-dependent viscosity. A suitable coordinate transformation is used to transform the governing equations into nonsimilar boundary layer solutions, and the cubic spline collocation method is then employed to solve the obtained governing equations. The local Nusselt number is presented as functions of suction variables for different values of viscosity-variation parameter, surface temperature exponent, and Prandtl number. Results show that an increase in the suction variable or the viscosity-variation parameter tends to increase the local Nusselt number of the vertical permeable cones with temperature-dependent viscosity. The effect of the viscosity-variation parameter on the local Nusselt number is significant only for small values of suction variables.
