Petascale Brownian dynamics simulations of highly resolved polymer chains with hydrodynamic interactions using modern GPUs
Venkata Siva Krishna, Praphul Kumar, Bharatkumar Sharma +1
Brownian dynamics simulations of fairly long, highly detailed polymer chains, at the resolution of a single Kuhn step, remains computationally prohibitive even on the modern proces…
Effects of chain resolution on the configurational and rheological predictions from Brownian dynamics simulations of an isolated polymer chain in flow
Praphul Kumar, Indranil Saha Dalal
A reasonably accurate representation of a polymer chain is provided by beads connected with rods, or stiff, inextensible springs that mimic a single Kuhn step. Due to high computat…
Formulation of an equivalent GNF model as an efficient approximation for flow of polymer solutions described by FENE-P
Anirban Ghosh, Raghav Kumar, Indranil Saha Dalal
The molecular constitutive models, like FENE-P for polymer solutions, are known to have convergence issues at relatively larger flow rates. In this study, we investigate the possib…
