Interfacial Dynamics at Micro and Nanoconfinements
Embedded Files
In the varying cross-sectional nanopore, the characteristic length scale progressively approaches molecular dimensions as the passage converges.
Complex interplay between upstream flow conditions and the fundamental attributes of interfacial layering in downstream locations.
The multiscale modelling coupling MD and CFD serves a great deal to investigate flow instances and velocity profiles.

Ion water interaction within varying nanoconfinement under the influence of external electric fields
To investigate the influence of surface wetting characteristics, concentration, and external field on the ion dynamics and flow characteristics within varying cross-sectional nanoconfinement.
Ionic currents in nanochannels portray non-linear behaviour.
ICR (ion current rectification) and ICP (ion current polarisation) towards biomedical devices, flow controls, synthesis, separation, iontronics, and lab-on-chips.
Countless non-trivial characteristics under the influence of solution properties, channel configurations, wall physicochemical properties, and external stimuli.
Potential Applications:

Micro-nanofluidic Diode
Potential Applications:
Drug delivery, flow control devices, lab-on-chip and organ-on-chip devices.
The linear correspondence between flow rate and pressure drop for low Reynolds number hydrodynamics is often a constraint for the realization of miniaturized fluid circuits with selective junctions.
Here, we devise a micro-nanochannel junction with the directional flow in the nanochannel achieved by a combination of junction geometry and wall functionalization.

Fluid Flow through Tree Shaped Microchannel Network
This model is inspired by tree structures. As each branch distributes food and water within several branches efficiently, our fluid channel system supplies fluid in several branches, which may enhance heat transfer within the system.
This type of plate may find applications in electronic chip cooling and other heat transfer applications.
A larger scale model is being developed to be used in building tiles so that the building can be more energy efficient, especially in a hot summer day.
Dynamic flow characteristics in nanofluidics
Dynamic behaviour is observed in the water interface within the varying nanoconfinement.
The interfacial properties may not necessarily depend on the local physio-chemical properties but astonishingly depend on the upstream flow characteristics.
The water ion may additionally possess non-intuitive flow characteristics.
