Abstract: In this paper, we have investigated the propagation properties of a partially coherent vortex cosine-hyperbolic-Gaussian beam (PCvChGB) propagating in weak oceanic turbulence. We established the analytical expression of the average intensity of the PCvChGB based… read more here.

Abstract: It is well known that an inverse turbulent cascade in a finite (2π×2π) two-dimensional periodic domain leads to the emergence of a system-sized coherent vortex dipole. We report a numerical hyperviscous study of the spatial… read more here.

Abstract: The evolution of a vortex flow excited by an electromagnetic technique in a thin layer of a conducting liquid was studied experimentally. Small-scale vortices, excited at the pumping scale, merge with time due to the… read more here.

DOI: 10.1364/oe.539069
Abstract: In structured light tweezers, enhancing control precision and degrees of freedom in optical manipulation remains a significant technical challenge. Traditional optical tweezers, which rely on a three-dimensional adjustable displacement platform, inherently limit both control precision… read more here.

DOI: 10.3390/en17112725
Abstract: This work investigates the dynamics of heavy particles dispersed in turbulent channel flows under unstable thermal stratification conditions using point-particle direct numerical simulations (PP-DNS), to quantify the influence of large-scale coherent vortex rolls, arising from… read more here.
