On the Applicability of Low-Dimensional Models for Convective Flow Reversals at Extreme Prandtl Numbers
Manu Mannattil, Ambrish Pandey, Mahendra K. Verma +1
Constructing simpler models, either stochastic or deterministic, for exploring the phenomenon of flow reversals in fluid systems is in vogue across disciplines. Using direct numeri…
Anisotropy in Quasi-Static Magnetohydrodynamic Turbulence
Mahendra K. Verma
In this review we summarise the current status of the quasi-static magnetohydrodynamic turbulence. The energy spectrum is steeper than Kolmogorov's spectrum due to the d…
Amplification of large-scale magnetic field in nonhelical magnetohydrodynamics
Rohit Kumar, Mahendra K. Verma
It is typically assumed that the kinetic and magnetic helicities play a crucial role in the growth of large-scale dynamo. In this paper we demonstrate that helicity is not essentia…
Dynamic anisotropy in MHD turbulence induced by mean magnetic field
Sita Sundar, Mahendra K. Verma, Alexandros Alexakis +1
In this paper, we study the development of anisotropy in strong MHD turbulence in the presence of a large scale magnetic field B 0 by analyzing the results of direct numerical simu…
Proper orthogonal decomposition vs. Fourier analysis for extraction of large-scale structures of thermal convection
Supriyo Paul, Mahendra K. Verma
We performed a comparative study of extraction of large-scale flow structures in Rayleigh Bénard convection using proper orthogonal decomposition (POD) and {\em Fourier analysis}.…
Discrete Symmetries in Dynamo Reversals
Riddhi Bandyopadhyay, Mahendra K. Verma
Quantification of the velocity and magnetic field reversals in dynamo remains an interesting challenge. In this paper, using group-theoretic analysis, we classify the reversing and…
