FOWT Stability Study According to Number of Columns Considering Amount of Materials Used

open access: yesEnergies, 2022
Considering stability and fabrication cost, 3–4 columns are usually adopted for semi-submersible platform designs. Although increasing the number of columns provides more stability for both floating platform and system as a whole, it is generally not ...

An expedition to the islands of stability in the first-order causal hydrodynamics

open access: yesPhysics Letters B, 2023
The recently proposed connection between the Lorentz invariance of stability and the speed of signal propagation has been tested for a first-order relativistic dissipative hydrodynamic theory.

Transversal inhomogeneities in dilute vibrofluidized granular fluids [PDF]

open access: yes, 2002
The spontaneous symmetry breaking taking place in the direction perpendicular to the energy flux in a dilute vibrofluidized granular system is investigated, using both a hydrodynamic description and simulation methods.

A Review on Hydrodynamical Stability of Thin Film Flowing Along an Inclined Plane

open access: yesJournal of Mathematical Sciences and Modelling, 2019
The dynamics and stability of thin liquid films have fascinated scientists over many decades. Thin film flows occur over a wide range of length scales and are central to numerous areas of engineering, geophysics and biophysics. These include nanofluidics

On non-linear hydrodynamic instability and enhanced transport in differentially rotating flows [PDF]

open access: yes, 2003
In this paper we argue that differential rotation can possibly sustain hydrodynamic turbulence in the absence of magnetic field. We explain why the non-linearities of the hydrodynamic equations (i.e.
