Journal ArticleDOI
Experimental studies and numerical simulation of evaporative cooling of air with a water spray—I. Horizontal parallel flow
TL;DR: In this article, a two-dimensional numerical model simulating the conservation of mass, momentum and energy of air, and water, was developed for predicting the heat and mass transfer in spray-air flow systems.
Journal ArticleDOI
Effects of interplay of nanoparticles, surfactants and base fluid on the surface tension of nanocolloids
A. R. Harikrishnan,Purbarun Dhar,Prabhat K. Agnihotri,Sateesh Gedupudi,Sarit K. Das,Sarit K. Das +5 more
TL;DR: The present paper conclusively explains several physical phenomena observed, yet hitherto unexplained, in the case of the surface tension of such complex fluids by segregating the individual contributions of each component of the colloidal system.
Journal ArticleDOI
The Role of Percolation and Sheet Dynamics during Heat Conduction in poly-dispersed Graphene Nanofluids
TL;DR: In this paper, a thermal transport mechanism leading to the enhanced thermal conductivity of Graphene nanofluids has been proposed, where the size of the sheet is considered to be the key to the underlying mechanism.
Journal ArticleDOI
The role of percolation and sheet dynamics during heat conduction in poly-dispersed graphene nanofluids
TL;DR: In this paper, a thermal transport mechanism leading to the enhanced thermal conductivity of graphene nanofluids has been proposed, and the graphene sheet size is postulated to be the key to the underlying mechanism.
Journal ArticleDOI
Percolation network dynamicity and sheet dynamics governed viscous behavior of polydispersed graphene nanosheet suspensions
Purbarun Dhar,Mohammad Hasan Dad Ansari,Soujit Sen Gupta,V. Manoj Siva,Thalappil Pradeep,Arvind Pattamatta,Sarit K. Das +6 more
TL;DR: In this article, a dimensionally consistent analytic model was proposed to determine and explain the viscosity of polydispersed GNSs, which was found to be in agreement with the GNS experimental data, and even for CNT (diameter 20nm, length 10μm) and nano-alumina (45nm) suspensions.
