Molecular Dynamics Simulation of Bubble Nucleation in Hydrophilic Nanochannels by Surface Heating
Manish Gupta, Shalabh C. Maroo
Bubble nucleation in liquid confined in nanochannel is studied using molecular dynamics simulations and compared against nucleation in the liquid over smooth (i.e. without confinem…
Disjoining Pressure Driven Transpiration of Water in a Simulated Tree
Sajag Poudel, An Zou, Shalabh C. Maroo
We present an investigation of transpiration of water in a 100 m tall tree using continuum simulations. Disjoining pressure is found to induce absolute negative pressures as high a…
Implementation of Near-Surface Disjoining Pressure Effect in Continuum Simulations
Sajag Poudel, An Zou, Shalabh C. Maroo
An expression of disjoining pressure in a water film, as a function of distance from the surface, is developed from prior experimental findings. The expression is implemented in co…
Thermal Management of Photovoltaics using Porous Nanochannels
Sajag Poudel, An Zou, Shalabh C. Maroo
The photoelectric conversion efficiency of a solar cell is dependent on its temperature. When the solar radiation is incident on the photovoltaics (PV) panel, a large portion of it…
Nano-Confinement Effects on Liquid Pressure
An Zou, Shalabh C. Maroo
In this work, molecular dynamics simulations are performed to estimate the equilibrium pressure of liquid confined in nanopores. The simulations show that the pressure is highly se…
Droplet Evaporation on Porous Nanochannels for High Heat Flux Dissipation
Sajag Poudel, An Zou, Shalabh C. Maroo
Droplet wicking and evaporation in porous nanochannels is experimentally studied on a heated surface at temperatures ranging from 35oC to 90oC. The fabricated geometry consists of…
Disjoining Pressure of Water in Nanochannels
An Zou, Sajag Poudel, Manish Gupta +1
Experiments of water wicking in 1D silicon-dioxide nanochannels of heights 59 nm, 87 nm, 124 nm and 1015 nm are used to estimate the disjoining pressure of water which was found to…
A Direct Two-Dimensional Pressure Formulation in Molecular Dynamics
Sumith Yesudasan, Sibi K. Chacko
Two-dimensional (2D) pressure field estimation in molecular dynamics (MD) simulations has been done using three-dimensional (3D) pressure field calculations followed by averaging,…
A new algorithm for contact angle estimation in molecular dynamics simulations
Sumith YD, Shalabh C. Maroo
It is important to study contact angle of a liquid on a solid surface to understand its wetting properties, capillarity and surface interaction energy. While performing transient m…
