Evaporation of nanofluid droplet on heated surface

Advances in Mechanical Engineering, 2015
In this study, an experiment on the evaporation of nanofluid sessile droplet on a heated surface was conducted. A nanofluid of 0.5% volumetric concentration mixed with 80-nm-sized CuO powder and pure water were used for experiment. Droplet was applied to

Three dimensional features of convective heat transfer in droplet-based microchannel heat sinks [PDF]

, 2015
Convective heat transfer in droplet-based microchannel heat sinks can be enhanced by the recirculating vortices due to the presence of interfaces. In rectangular microchannels, the three dimensional structures of the vortices and the ‘gutters’ (i.e., the

Evaporative Heat Transfer from an Electrowetted Liquid Ribbon on a Heated Substrate

, 2013
Evaporation of narrow water ribbons (of 5 and 7 lL volume) formed on a heated surface is investigated. Chemical and structural patterning of a silicon substrate is employed to fabricate a hydrophilic stripe that bisects hydrophobic pillar arrays of ...

Fundamental studies of combustion of droplet and vapour mixtures [PDF]

, 2010
There are few experimental data of a fundamental nature that clearly demonstrate the similarities and differences in burning rates between single phase and two phase combustion, either in laminar or turbulent conditions. Such data are essential towards a
