Abstract The problem of free convection from a fin situated in a quiescent non-Newtonian medium exhibiting power law relation between the rate of angular deformation and the shear stress is theoretically investigated. The equation of thermal diffusion in the fin is coupled to the constitutive equations of the medium set to motion due to the buoyant forces. The analysis is accomplished by treating equations in integral form. The results obtained indicate profound influence of the fin parameter and the flow behaviour index of the power law on the local and average heat transfer coefficients. The results further reveal that for a wide range of fin parameters, the local heat transfer coefficients are exhibiting non-monotonically varying characteristics along the length of the fin. The results are manipulated by the method of regression to compute the average heat transfer coefficient as a function of the modified Rayleigh number, fin parameter and the flow behaviour index.
