We analyze the effect of an external flow on the rheological and magnetic properties of a suspension of non-interacting magnetic dipoles in a Newtonian non-polar fluid (ferrofluid). The friction for a dipole moving through this fluid, which is in a state of elongational flow, is computed. A...

Fluctuations about homogeneous and inhomogeneous non-equilibrium steady states near Gunn instability are studied. Density and electric field autocorrelation functions in Fourier and real spaces are calculated in the framework of generalized Landau-Lifshitz fluctuating hydrodynamics. Some...

We study the propagation of the temperature fluctuations in a system in the presence of an interface. Such fluctuations originate from surface noise sources which are introduced through the random parts of the interfacial currents which satisfy fluctuation-dissipation theorems. The formal...

By considering an ensemble of Brownian particles suspended in a heat bath as a thermodynamic system with an internal degree of freedom it is possible to obtain the Fokker-Planck equation for Brownian motion in a temperature gradient, by applying the scheme of non-equilibrium thermodynamics. We...

Our previous work in which we have computed the stationary correlation functions of positions and momenta in the “harmonic liquid” is now extended to get the expressions of the time-dependent correlation functions of such quantities. The static and dynamic structure factors are computed. The...

The methods of non-equilibrium thermodynamics of systems with an interface have been applied to the study of thermionic emission processes in abrupt semiconductor junctions, including the effects of surface states. Our analysis covers different situations of interest, concerning unipolar and...

Interfacial immiscible fluid systems with hydrodynamic spin are studied within the framework of non-equilibrium thermodynamics. The energy and entropy densities and the momentum, internal angular momentum and heat currents are allowed to be singular at the interface. Balance equations in the...

A method of induced forces and torques is employed to study brownian motion of a particle in a fluid with internal angular momentum (spin). One derives generalized Faxén theorems for the force and torque exerted on the particle. In the Landau-Lifshitz approach, one obtains...

The dynamic structure factor of a suspension moving through a fluid with spin (suspension of dipolar particles in the continuum limit) is computed. Two situations are treated, namely when the system is in equilibrium and when a velocity gradient is present. In the first case we get a correction...

A scheme introduced recently for the description of non-linear hydrodynamic fluctuations of a one-component fluid is extended to the case of a two-component charged fluid. The random fluxes which are introduced are assumed to be Gaussian processes with white noise. It is found that the usual...
