Gaussian field model for polar fluids as a function of density and polarization: toward a model for water

, 2017
This work is concerned with a simple model for a polar fluid, a Gaussian field model based on the excess density and on the polarization. It is a convenient framework to implement the dielectric properties of correlated liquids that stem from nanometric ...

Time dependent couplings in the dark sector: from background evolution to nonlinear structure formation

, 2010
We present a complete numerical study of cosmological models with a time dependent coupling between the dark energy component driving the present accelerated expansion of the Universe and the Cold Dark Matter (CDM) fluid. Depending on the functional form

Unsteady Analyses of a Control Valve due to Fluid-Structure Coupling

, 2013
Control valves play important roles in the control of the mixed-gas pressure in the combined cycle power plants (CCPP). In order to clarify the influence of coupling between the structure and the fluid system at the control valve, the coupling mechanism ...

Vortical fluid and $\Lambda$ spin correlations in high-energy heavy-ion collisions

, 2016
Fermions become polarized in a vortical fluid due to spin-vorticity coupling. The spin polarization density is proportional to the local fluid vorticity at the next-to-leading order of a gradient expansion in a quantum kinetic theory.
