Controlling droplet motion on engineered surfaces

Dr Pallab Sinha Mahapatra


Manipulation of fluids on an open surface can be done actively or passively. Wettability patterning is an approach to passive fluidic manipulation for its easy accessibility, ease of fabrication, and low cost. Wettability patterning can be done through surface engineering, which can be performed at both the micro and nano-scale. This approach is not limited to solid surfaces but can also be applied to porous substrates.

A detailed investigation of fluid manipulation on different wettability pattern surfaces is missing, and an effort is being made through numerical simulation, theoretical analysis, and experiments to optimize the pattern and investigate the fluid dynamics on the patterned wettable surfaces. Wettability pattern is shown in condensation, spray cooling, identification of milk adulterants, etc.<?p>
