Abstract: In this paper we present a detailed description of the statistical and computational techniques that were employed to study a driven far-from-equilibrium steady-state Rayleigh-B{e}nard system in the non-turbulent regime ($Ra\leq 3500$). In our previous work… read more here.

DOI: 10.1016/j.physa.2022.126985
Abstract: An approach that extends equilibrium thermodynamics principles to out-ofequilibrium systems is based on the local equilibrium hypothesis. However, the validity of the a priori assumption of local equilibrium has been questioned due to the lack… read more here.

DOI: 10.1017/jfm.2019.85
Abstract: The average patterns of the velocity and scalar fields near turbulent/non-turbulent interfaces (TNTI), obtained from direct numerical simulations (DNS) of planar turbulent jets and shear free turbulence, are assessed in the strain eigenframe. These flow… read more here.

DOI: 10.1017/jfm.2020.241
Abstract: The highly convoluted interface separating the turbulent and non-turbulent regions in a turbulent mixing layer is experimentally investigated using the particle image velocimetry (PIV) technique. The mixing layer was generated using a fine screen/mesh in… read more here.

DOI: 10.5194/bg-17-3247-2020
Abstract: Abstract. The East Siberian Arctic Shelf (ESAS) hosts large yet poorly quantified reservoirs of subsea permafrost and associated gas hydrates. It has been suggested that the global-warming induced thawing and dissociation of these reservoirs is… read more here.
