Bioluminescence in turbulence: intermittent straining lights up dinoflagellates
Praphul Kumar, Jason R. Picardo
Dinoflagellates are marine phytoplankton that emit flashes of light in response to flow-induced deformation; they are responsible for illuminating breaking-waves, wakes of ships, a…
Tunability of Dissipative Particle Dynamics simulations for Excluded Volume and Hydrodynamic Interactions in polymer solutions and Rheological predictions
Sanjay Jana, Venkata Siva Krishna, Praphul Kumar +1
Even though the Dissipative Particle Dynamics (DPD) has shown its worth in a variety of research areas, it has been rarely used for polymer dynamics, particularly in dilute and sem…
Gravity modes on rapidly rotating accreting white dwarfs and their variation after dwarf novae
Praphull Kumar, Dean M. Townsley
Accreting white dwarfs in Cataclysmic variables (CVs) show short-period (tens of minutes) brightness variations that are consistent with non-radial oscillations similar to gravity…
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…
Dissipative particle dynamics simulations of a single isolated polymer chain in a dilute solution
Praphul Kumar, Harishyam, Indranil Saha Dalal
In this study, we investigate the suitability of dissipative particle dynamics (DPD) simulations to predict the dynamics of polymer chains in dilute polymer solutions, where the ch…
