Direct Numerical Simulations of Three-dimensional Magnetohydrodynamic Turbulence with Random, Power-law Forcing
Ganapati Sahoo, Nadia Bihari Padhan, Abhik Basu +1
We present pseudospectral direct-numerical-simulation (DNS) studies of the three-dimensional magnetohydrodynamic (MHD) equations (3DRFMHD) with a stochastic force that has zero mea…
The Statistical Properties of Superfluid Turbulence in He from the Hall-Vinen-Bekharevich-Khalatnikov Model
Akhilesh Kumar Verma, Sanjay Shukla, Vishwanath Shukla +2
We obtain the von Kármán-Howarth relation for the stochastically forced three-dimensional Hall-Vinen-Bekharvich-Khalatnikov (3D HVBK) model of superfluid turbulence in Helium (…
The analogue Hawking effect in rotating polygonal hydraulic jumps
Arnab K. Ray, Niladri Sarkar, Abhik Basu +1
Rotation of non-circular hydraulic jumps is a recent experimental observation that lacks a theory based on first principles. Here we furnish a basic theory of this phenomenon found…
