A weighted particle scheme for Enskog-Vlasov equation to simulate spherical nano-droplets/bubbles

چکیده

The Enskog-Vlasov equation has been proven successful in capturing the complex behaviour of fluids undergoing a phase change. However, its numerical solution is computationally demanding, and this restricted studies to one- two-dimensional planar flows. In work, weighted particle scheme developed for Enskog–Vlasov spherically symmetric geometry. It shown how schemes designed Boltzmann can be extended cope with non-local structure Enskog collision integral, compact expression mean force field determined using shell theorem. As an application, growth rates nano-droplets/bubbles bulk homogeneous metastable vapour/liquid are evaluated wide range supersaturation ratios that was not possible until now due high computational cost required by alternate approaches. proposed significantly broadens problems investigated via equation, it stepping stone towards simulation general three-dimensional liquid-vapour

Grid-free Particle Method for the Inhomogeneous Enskog Equation and Its Application to a Riemann-problem

Starting from the molliied version of the Enskog equation for a hard-sphere uid, a grid-free algorithm to obtain the solution is proposed. The algorithm is based on the nite pointset method. For illustration, it is applied to a Riemann problem. The shock-wave solution is compared to the results of Frezzotti and Sgarra where a good agreement is found.

Particle-in-wavelets Scheme for the 1d Vlasov-poisson Equations

A new numerical scheme called particle-in-wavelets is proposed for the Vlasov-Poisson equations, and tested in the simplest case of one spatial dimension. The plasma distribution function is discretized using tracer particles, and the charge distribution is reconstructed using wavelet-based density estimation. The latter consists in projecting the Delta distributions corresponding to the partic...

Trend to equilibrium and particle approximation for a weakly selfconsistent Vlasov-Fokker-Planck equation

We consider a Vlasov-Fokker-Planck equation governing the evolution of the density of interacting and diffusive matter in the space of positions and velocities. We use a probabilistic interpretation to obtain convergence towards equilibrium in Wasserstein distance with an explicit exponential rate. We also prove a propagation of chaos property for an associated particle system, and give rates o...

The Modified Enskog Equation for Mixtures

synopsis In a previous paper it was shown that a modified form of the Enskog equation, applied to mixtures of hard spheres, should be considered as the correct extension of the usual Enskog equation to the case of mixtures. The main argument was that the modified Enskog equation leads to linear transport coefficients which are in complete agreement with the laws of irreversible thermodynamics. ...

A Relaxation Scheme for Solving the Boltzmann Equation Based on the Chapman-Enskog Expansion

In [16] a visco-elastic relaxation system, called the relaxed Burnett system, was proposed by Jin and Slemrod as a moment approximation to the Boltzmann equation. The relaxed Burnett system is weakly parabolic, has a linearly hyperbolic convection part, and is endowed with a generalized entropy inequality. It agrees with the solution of the Boltzmann equation up to the Burnett order via the Cha...
