A phenomenological approach to COVID-19 spread in a population
Anantanarayanan Thyagaraja
A phenomenological model to describe the Corona Virus(covid-19) Pandemic spread in a given population is developed. It enables the identification of the key quantities required to…
Simulation of the internal kink mode in visco-resistive regimes
Jervis Mendonca, Debasis Chandra, Abhijit Sen +1
We present numerical simulation results of the nonlinear evolution of the (1,1) internal kink mode in the presence of various kinds of equilibrium plasma flows. The present studies…
Nonlinear dispersive regularization of inviscid gas dynamics
Govind S Krishnaswami, Sachin Phatak, Sonakshi Sachdev +1
Ideal gas dynamics can develop shock-like singularities with discontinuous density. Viscosity typically regularizes such singularities and leads to a shock structure. On the other…
Numerical simulation of the effect of pellet injection on ELMs
D Chandra, A Sen, A Thyagaraja
We report on numerical simulation studies of the dynamical behavior of edge localized modes (ELMs) under the influence of repetitive injection of pellets. In our nonlinear 2-fluid…
Conservative regularization of compressible dissipationless two-fluid plasmas
Govind S. Krishnaswami, Sonakshi Sachdev, Anantanarayanan Thyagaraja
This paper extends our earlier approach [cf. Phys. Plasmas 17, 032503 (2010), 23, 022308 (2016)] to obtaining a priori bounds on enstrophy in neutral fluids (R-Euler) and ideal mag…
Visco-resistive MHD study of internal kink(m=1) modes
Jervis Mendonca, Debasis Chandra, Abhijit Sen +1
We have investigated the effect of sheared equilibrium flows on the resistive internal kink mode in the framework of a reduced magnetohydrodynamic model in a periodi…
