Constraining the radial decay timescale of solar surface magnetic field through a comparative study of data-assimilative 2D surface flux transport and 3D dynamo models
Soumyadeep Chatterjee, Gopal Hazra
The polar magnetic field is the most reliable precursor for predicting the amplitude of the solar cycle, and the 2D surface flux transport (SFT) model is widely used to reconstruct…
Probing the large-scale magnetic field inside the Sun from three decades of observed surface magnetograms
Soumyadeep Chatterjee, Gopal Hazra
Space-weather and disturbances in the heliosphere are manifestations of the solar magnetic field, which is solely driven by the interior dynamo, and constraining the solar interior…
Equilibrium and nonequilibrium properties of Euler turbulence
Mahendra K. Verma, Soumyadeep Chatterjee
In this article, we report the equilibrium and nonequilibrium features of two-dimensional (2D) and three-dimensional (3D) Euler turbulence. To obtain a full range of equilibrium sp…
Turbulent Drag Reduction in Magnetohydrodynamic Turbulence and Dynamo from Energy Flux Perspectives
Mahendra K. Verma, Manohar K. Sharma, Soumyadeep Chatterjee
In this review, we describe turbulent drag reduction in a variety of flows using a universal framework of energy flux. In a turbulent flow with dilute polymers and magnetic field,…
Hydrodynamic Entropy and Emergence of Order in Two-dimensional Euler Turbulence
Mahendra K. Verma, Soumyadeep Chatterjee
Using numerical simulations, we show that the asymptotic states of two-dimensional (2D) Euler turbulence exhibit large-scale flow structures due to nonzero energy transfers among s…
Equilibrium states of Burgers and KdV equations
Mahendra K. Verma, Soumyadeep Chatterjee, Aryan Sharma +1
We simulate KdV and dissipation-less Burgers equations using delta-correlated random noise as initial condition. We observe that the energy fluxes of the two equations remain zero…
