Interfacial temperature measurements, high-speed visualization and finite-element simulations of droplet impact and evaporation on a solid surface
Rajneesh Bhardwaj, Jon P. Longtin, Daniel Attinger
The objective of this work is to investigate the coupling of fluid dynamics, heat transfer and mass transfer during the impact and evaporation of droplets on a heated solid substra…
Self-assembly of colloidal particles from evaporating droplets: role of DLVO interactions and proposition of a phase diagram
Rajneesh Bhardwaj, Xiaohua Fang, Ponisseril Somasundaran +1
The shape of deposits obtained from drying drops containing colloidal particles matters for technologies such as inkjet printing, microelectronics and bioassay manufacturing. In th…
Pattern formation during the evaporation of a colloidal nanoliter drop: a numerical and experimental study
Rajneesh Bhardwaj, Xiaohua Fang, Daniel Attinger
An efficient way to precisely pattern particles on solid surfaces is to dispense and evaporate colloidal drops, as for bioassays. The dried deposits often exhibit complex structure…
A numerical investigation on the influence of liquid properties and interfacial heat transfer during microdroplet deposition onto a glass substrate
Rajneesh Bhardwaj, Jon P. Longtin, Daniel Attinger
This work investigates the impingement of a liquid microdroplet onto a glass substrate at different temperatures. A finite-element model is applied to simulate the transient fluid…
Non-isothermal wetting during impact of millimeter size water drop on a flat substrate: numerical investigation and comparison with high-speed visualization experiments
Rajneesh Bhardwaj, Daniel Attinger
The objective of this work is to develop and validate a numerical model to study wetting during the impact of millimeter-size drops on a flat, smooth, solid substrate under isother…
Do surfaces with mixed hydrophilic and hydrophobic areas enhance pool boiling?
Amy Betz, Jie Xu, Huihe Qiu +1
We demonstrate that smooth and flat surfaces combining hydrophilic and hydrophobic patterns improve pool boiling performance. Compared to a hydrophilic surface with 7 degree wettin…
