Abstract: In the present work, investigation was carried out to study the suitability of vegetable oil blends with mineral oil and alumina based nanofiuids as quench media for heat treatment. Palm oil, sunflower oil, gingili oil were blended with mineral oil in the ratio of 2:1, 3:1, 1:1, 1:2, and 1:3... Heat transfer coefficients were determined using a lumped heat capacitance model. A dynamic contact angle analyzer was used for determination of dynamic and static contact angle of the droplet on the substrate. The wetting behaviour of oils and their blends was modelled by a power law of the type: ? = ktn. Wettability of nanofiuids was found to be poor.
