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…
Scalable Multi-node Fast Fourier Transform on GPUs
Manthan Verma, Soumyadeep Chatterjee, Gaurav Garg +5
In this paper, we present the details of our multi-node GPU-FFT library, as well its scaling on Selene HPC system. Our library employs slab decomposition for data division and MPI…
