Generalized Onsager-Regularized Lattice Boltzmann Method for error-free Navier-Stokes models on standard lattices

Anirudh Jonnalagadda, Walter Rocchia, Sauro Succi

This work presents a novel strategy to address Navier-Stokes modelling errors arising on first-nearest neighbour lattice Boltzmann (LB) methods and introduces fully local correctio…

Exact Screening-Ranged Expansions for Many-Body Electrostatics

Sergii V. Siryk, Walter Rocchia

We present an exact many-body framework for electrostatic interactions among arbitrarily charged spheres in an electrolyte, modeled by the linearized Poisson--Boltzmann equatio…

Many interacting particles in solution. III. Spectral analysis of the associated Neumann--Poincaré-type operators

Sergii V. Siryk, Walter Rocchia

The interaction of particles in an electrolytic medium can be calculated by solving the Poisson equation inside the solutes and the linearized Poisson--Boltzmann equation in the so…
