Abstract
A comparative study is done to understand the effect of variation in surface energy of substrates on boiling and
dry-out characteristics of nanofluid. Droplet of TiO2 nanofluid on glass substrate shows strong pinning along
the droplet perimeter. As the droplet evaporates, boundary of nanofluid droplet recedes slowly towards the
center leaving a ring-shaped stain of concentrated nanoparticles. Surface energy of glass substrate is modified
by graphene coating, confirmed by increase in contact angle. While boiling of nanofluid on graphene coated
glass substrate shows an almost uniform dry-out pattern. Reduced wettability of nanofluid droplet on graphene
coated glass substrate is responsible for this behavior.
