A numerical study on the coefficient of restitution of wet collisions
Abhishek Kumar Singh, Christopher Robert Kit Windows-Yule, Prapanch Nair
Using smoothed particle hydrodynamics (SPH) simulations, we investigate the coefficient of restitution (COR) in wet collisions and identify a scaling law governing its behavior. Th…
A numerical study on the effect of rolling friction on clogging of pores in particle-laden flows
Sagar G. Nayak, Zhenjiang You, Yuchen Dai +2
Particulate matter in a fluid injected into a porous reservoir impairs its permeability spatio-temporally due to pore clogging. As particle volume fraction increases near the pore…
A three-dimensional numerical scheme for modeling three-phase contact line pinning using Smoothed Particle Hydrodynamics
Subrat Kumar Nayak, Amitabh Bhattacharya, Prapanch Nair
In several capillary dynamics experiments, the liquid domain is confined by pinning the three-phase contact line along a sharp edge or a discontinuity on the substrate. Simulating…
An Eulerian Meshless Method for Two-phase Flows with Embedded Geometries
Anand S Bharadwaj, Pratik Suchde, Prapanch Nair
We present a novel Eulerian meshless method for two-phase flows with arbitrary embedded geometries. The spatial derivatives are computed using the meshless generalized finite diffe…
Surface tension and wetting at free surfaces in Smoothed Particle Hydrodynamics
Michael Blank, Prapanch Nair, Thorsten Pöschel
Surface tension and wetting are dominating physical effects in micro and nanoscale flows. We present an efficient and reliable model of surface tension and equilibrium contact angl…
Can Minkowski tensors of a porous microstructure characterize its permeability?
Prapanch Nair, Sebastian Mühlbauer, Shantanu Roy +1
We show that the permeability of porous media can be reliably predicted from the Minkowski tensors (MTs) describing the pore microstructure geometry. To this end, we consider a lar…
Multiphase flows with compressible and incompressible phases
Prapanch Nair, Gaurav Tomar
Gas bubbles immersed in a liquid and flowing through a large pressure gradient undergoes volumetric deformation in addition to possible deviatoric deformation. While the high densi…
Influence of capillary viscous flow on melting dynamics
Michael Blank, Prapanch Nair, Thorsten Pöschel
The rate of melting of a solid and the rate of deformation of the resulting melt due to capillary forces are comparable in additive manufacturing applications. This dynamic structu…
Dynamic capillary phenomena using Incompressible SPH
Prapanch Nair, Thorsten Poeschel
Grid based fluid simulation methods are not able to monolithically capture complex non-linear dynamics like the rupture of a dynamic liquid bridge between freely colliding solids,…
