Large eddy simulations using renormalized viscosity
Sumit Vashishtha, Anando Chatterjee, Abhishek Kumar +1
In this paper, we have used renormalized viscosity for performing large eddy simulations (LES) of decaying homogeneous and isotropic turbulence inside a periodic cube on coarse gri…
Energy Spectra and Fluxes in Dissipation Range of Turbulent and Laminar Flows
Mahendra K. Verma, Abhishek Kumar, Praveen Kumar +4
Two well-known turbulence models that describe the energy spectrum in the inertial and dissipative ranges simultaneously are by Pao~(1965) and Pope~(2000). In this paper, we comput…
Surface Ocean Enstrophy, Kinetic Energy Fluxes and Spectra from Satellite Altimetry
Hemant Khatri, Jai Sukhatme, Abhishek Kumar +1
Enstrophy, kinetic energy (KE) fluxes and spectra are estimated in different parts of the mid-latitudinal oceans via altimetry data. To begin with, using geostrophic currents deriv…
