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…
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…
Characteristics of shock tube generated compressible vortex rings at very high shock Mach numbers
Sajag Poudel, Chandrala Lakshmana Dora, Ashoke De +1
Compressible vortex rings, usually formed at the open end of a shock tube, often show interesting phenomena during their formation, evolution, and propagation depending on the shoc…
