Heat capacity of liquids: A hydrodynamic approach

Condensed Matter Physics, 2015
We study autocorrelation functions of energy, heat and entropy densities obtained by molecular dynamics simulations of supercritical Ar and compare them with the predictions of the hydrodynamic theory.

Resurgence and hydrodynamic attractors in Gauss-Bonnet holography

Journal of High Energy Physics, 2018
We study the convergence of the hydrodynamic series in the gravity dual of Gauss-Bonnet gravity in five dimensions with negative cosmological constant via holography.

Diffusion and instabilities in large-N holographic Fermi liquids: the vector fluctuations of the electron star

Journal of High Energy Physics
We study the hydrodynamic response of the AdS electron star in the vector sector, and compute the correlation functions and the transverse conductivity of the dual field theory.

Hydrodynamic limit for interacting Ornstein–Uhlenbeck particles

Stochastic Processes and their Applications, 2002
Let us consider a system of \(N\) interacting Ornstein-Uhlenbeck particles, described by a stochastic differential equation \[ dq_ {i} = v_ {i}\,dt, \quad dv_ {i} = -2\sum _ {i\neq j} \nabla V(q_ {i}- q_ {j})\,dt - \frac {\gamma }2 v_ {i}\,dt + \sqrt {\frac {\gamma }{\beta }}\,dW_ {i}, \quad 1\leq i\leq N, \] in \((\mathbb T^ {d}\times \mathbb R^ {d})^

Hydrodynamics without boost-invariance from kinetic theory: From perfect fluids to active flocks

SciPost Physics
We derive the hydrodynamic equations of perfect fluids without boost invariance [J. de Boer et al., SciPost Phys. 5, 003 (2018)] from kinetic theory. Our approach is to follow the standard derivation of the Vlasov hierarchy based on an a-priori unknown ...

Non-Perturbative Hydrodynamic Limits

, 2013
We introduce non-perturbative analytical techniques for the derivation of the hydrodynamic manifolds from kinetic equations. The new approach is analogous to the Schwinger-Dyson equation of quantum field theories, and its derivation is demonstrated with the construction of the exact diffusion manifold for a model kinetic equation. The novel approach is

Heave Plate Shape Effects on the Motion Performance of 15 MW Floating Offshore Wind Turbine

Energies
Floating offshore wind turbines (FOWTs) are essential for meeting global renewable energy goals, yet their viability depends strongly on platform motion in harsh marine environments and the resulting influence on structural loading and the levelized cost

Hydrodynamic states of phonons in insulators

Condensed Matter Physics, 2012
The Chapman-Enskog method is generalized for accounting the effect of kinetic modes on hydrodynamic evolution. Hydrodynamic states of phonon system of insulators have been studied in a small drift velocity approximation. For simplicity, the investigation

Numerical Simulation of Highly Charged Droplets Dynamics with Primary Break-up in Electrospray at Sub Rayleigh Limit

Journal of Applied Fluid Mechanics, 2017
The size and the axial and radial velocity distributions of electrically controlled droplets generated from Taylor cone operating in the stable cone-jet regime are simulated by numerical modeling of electrosprays.
