Sweeping effect and Taylor's hypothesis via correlation function
Mahendra Kumar Verma, Abhishek Kumar, Akanksha Gupta
We demonstrate the sweeping effect in turbulence using numerical simulations of hydrodynamic turbulence without a mean velocity. The velocity correlation function, C(k, τ ) decays…
Energy and enstrophy spectra and fluxes for the inertial-dissipation range of two-dimensional turbulence
Akanksha Gupta, Rohith Jayaram, Anando G. Chaterjee +3
In this paper, using Pao's conjecture [Y.-H. Pao, Phys. Fluids 11, 1371 (1968)], we derive expressions for the spectra and fluxes of kinetic energy and enstrophy for two-dimensiona…
Emergence of inertial waves from coherent vortex source in Yukawa medium
Akanksha Gupta, Rajaraman Ganesh
The evolution of isotropic, nondispersive, inertial wave, emerging from an unsteady initial coherent vortex is studied for strongly correlated Yukawa medium using 2D molecular dyna…
Viscoelastic effects on asymmetric two-dimensional vortex patterns in a strongly coupled dusty plasma
Akanksha Gupta, Rupak Mukherjee, Rajaraman Ganesh
Strongly coupled dusty plasma medium is often described as a viscoelastic fluid that retains its memory. In a flowing dusty plasma medium, vortices of different sizes appear when t…
