It is shown that the cooperation between short and mid range attraction in Lattice Boltzmann (LB) models with multi-range pseudo-potentials, permits achievement of phase-separation at liquid/vapor density ratios excess 1 : 500, nearly an order magnitude above current limits standard single-range LB models. Inspection configurations reveals this favourable behaviour results from a sizeable reduction spurious currents near liquid/vapour interface. The aforementioned enhancement ratio obtained...
A dynamic optimization strategy is presented to generate customized equations of state (EOS) for the numerical simulation non-ideal fluids at high density ratio. While stable branches analytical EOS are preserved, spinodal region self-tuned during simulation, in order compensate errors caused by discretization phase space. The employed permits readily setting sound speeds gas and liquid phases, thus allowing with (1 : 10 1 1000) compressibility ratios (250 1–25000 1). present technique...
In February 2017 the “Carbonaceous Aerosol in Rome and Environs (CARE)” experiment was carried out downtown to address following specific questions: what is color, size, composition, toxicity of carbonaceous aerosol Mediterranean urban background area Rome? The motivation this lack understanding types are responsible for severe risks human health posed by particulate matter (PM) pollution, how aerosols influence radiative balance. Physicochemical properties were characterised, relevant...
Efficient storage solutions that decouple energy use and production are pivotal for the green transition, due to non-controllable operation of solar wind power. In this scenario, hydrogen, in particular metal hydride storage, has shown excellent potential. paper we develop a mathematical model characterize several cylindrical Metal Hydride-Phase Change Material tank layouts determine improved configuration terms charge/discharge time We non-dimensional parameters guide design hybrid...
We discuss further developments of the finite-volume lattice Boltzmann formulation on unstructured grids. It is shown that method tolerates significant grid distortions without showing any appreciable numerical viscosity effects at second order in mesh size. A theoretical argument plausibility for such a property presented. In addition, set boundary conditions which permit to handle flows with open boundaries also introduced and numerically demonstrated case channel driven cavity flows.
Further research on both theoretical and practical aspects of a previously defined finite-volume formulation to integrate the Lattice Boltzmann equation (LBE) unstructured grids is presented. Moreover, additional explicit schemes for time discretisation are proposed. The method tested an impulsively started channel flow with aim exactly locating solid boundaries. Cavity simulations used measure inaccuracies due compressibility, grid effects. Finally, proposed has been against laminar over...
Abstract The simulation of multiphase flows is an outstanding challenge, due to the inherent complexity underlying physical phenomena and fact that are very diverse in nature, so laws governing their dynamics. In last two decades, a new class mesoscopic methods, based on minimal lattice formulation Boltzmann kinetic equation, has gained significant interest as efficient alternative continuum methods discretisation NS equations for non ideal fluids. this paper, three different models method...
In this paper, we use the lattice Boltzmann method with Bhatnagar-Gross-Krook linear collision operator to study flow physics induced by a rigid lamina undergoing moderately large harmonic oscillations in viscous fluid. We propose refill procedure for hydrodynamic quantities sites that are vicinity of oscillating lamina. The numerically estimated field is used compute complex function describes added mass and damping experienced Results numerical simulations validated against theoretical...
