Steady state extensional rheology of a dilute suspension of spheres in a dilute polymer solution
Arjun Sharma, Donald L. Koch
We investigate the steady-state extensional rheology of a dilute suspension of spherical particles in a dilute polymer solution. For a particle-free polymeric fluid, in addition to…
Spatio-temporal relationships between rainfall and convective clouds during Indian Monsoon through a discrete lens
Arjun Sharma, Adway Mitra, Vishal Vasan +1
The Indian monsoon, a multi-variable process causing heavy rains during June-September every year, is very heterogeneous in space and time. We study the relationship between rainfa…
Early evolution of optimal perturbations in a viscosity-stratified channel
Ritabrata Thakur, Arjun Sharma, Rama Govindarajan
This work shows how the early stages of perturbation growth in a viscosity-stratified flow are different from those in a constant-viscosity flow, and how nonlinearity is a crucial…
Analytic Reconstruction of a Two-Dimensional Velocity Field from an Observed Diffusive Scalar
Arjun Sharma, Irina I. Rypina, Ruth Musgrave +1
Inverting an evolving diffusive scalar field to reconstruct the underlying velocity field is an underdetermined problem. Here we show, however, that for two-dimensional incompressi…
Viability of detection by AMS of sudden features due to dark matter annihilation to positrons and electrons
Arjun Sharma
The Fermi experiment has measured the cosmic ray electron+positron spectrum and positron fraction [, and PAMELA has measured the positron fraction with be…
