Large-scale anisotropy in stably stratified rotating flows
(American Physical Society, 2014-08)
We present results from direct numerical simulations of the Boussinesq equations in the presence of rotation and/or stratification, both in the vertical direction. The runs are forced isotropically and randomly at small ...
Control of a modular multilevel matrix converter for unified power flow controller applications
(MDPI, 2020)
The modular multilevel matrix converter has been proposed as a suitable option for high power applications such as flexible AC transmission systems. Among flexible AC transmission systems, the unified power flow controller ...

Dispersal of fish eggs and larvae in a cascade of small hydropower plants with fish ladders
(Springer, 2020-10-10)
This study was conducted to investigate fish eggs and larvae dispersal in a river stretch influenced by small hydropower plants in Southeast Brazil. The main hypothesis is that the downstream dispersal of free-flowing eggs ...
Large-scale behavior and statistical equilibria in rotating flows
(American Physical Society, 2011-01)
We examine long-time properties of the ideal dynamics of three-dimensional flows, in the presence or not of an imposed solid-body rotation and with or without helicity (velocity-vorticity correlation). In all cases, the ...
Effect of Helicity and Rotation on the Free Decay of Turbulent Flows
(American Physical Society, 2009-06)
The self-similar decay of energy in a turbulent flow is studied in direct numerical simulations with and without rotation. Two initial conditions are considered: one nonhelical (mirror symmetric) and one with maximal ...
