Traditional technologies for the recycling of spent lithium-ion batteries (LIBs) mainly focus on reductive leaching, which often leads to total leaching rather than selective metals. As a result, loss valuable metal ions, particularly Li+, occurs in subsequent extraction processes, causing low efficiency Inspired by oxide-delithiation process materials science, here, advanced oxidation processes (AOPs) are first introduced selectively recover Li from LIBs during hydrometallurgical (oxidative...
Kinetic theory is a common choice for closing the solid phase stress in continuum dilute and moderate dense gas–solid flows. In this article, methods are proposed postprocessing data obtained from discrete particle simulations, results then used to critically assess fundamental assumptions of kinetic theory. It shown that (i) predictions are, respectively, valid accurate homogeneous granular flows, as expected. Those prove effective; (ii) case nonequilibrium heterogeneous nearly all get...
The particle stress tensor is an indispensable part of continuum theory for gas–solid flow. In this study, computational fluid dynamics–discrete element method (CFD–DEM) simulations were performed to extract the in gas-fluidized beds. It was shown that numerically extracted pressures exerted on wall are excellent agreement with experimental data available literature, thus offering a direct validation approach extracts using CFD–DEM method. Furthermore, it found (i) bubble motion main source...
With the arrival of era big data and rapid development high-precision discrete simulations, a wealth high-quality is readily available, but discovering physical laws from these remains great challenge. In this study, an attempt made to discover governing equation granular flow for homogeneous cooling state element method (DEM) through sparse regression. It shown that not only also energy dissipation rate can be obtained accurately DEM systems having different properties particles operating...
Numerical solution of Euler-Euler model using different in-house, open source and commercial software can generate significantly results, even when the governing equations initial boundary conditions are exactly same. Unfortunately, underlying reasons have not been identified yet. In this article, three methods for calculating granular pressure gradient term presented two-fluid gas-solid flows implemented implicitly or explicitly into solver in OpenFOAM: Method I assumes that is equal to...
Polydisperse gas-solid flows, which is notoriously difficult to model due the complex gas-particle and particle-particle interactions, are widely encountered in industry. In this article, a refined kinetic theory for polydisperse flow developed, features single-parameter Chapman-Enskog expansion (the Knudsen number) exact calculation of integrations related pair distribution function particle velocity without any mathematical approximations. The Navier-Stokes order constitutive relations...
