The revised Enskog kinetic theory ~RET! for a system of hard spheres provides an exceptionally broad description of mesoscopic and macroscopic dynamics, applicable for both fluid and solid phases, long and short wavelengths, low and high densities, and exact at short times. This great potential is compromised by the difficulty of obtaining solutions outside the domain of linear response. In the...
We present a simulation scheme based on the lattice-Boltzmann method to simulate the dynamics of charged colloids in an electrolyte. In our model we describe the electrostatics on the level of a Poisson-Boltzmann equation and the hydrodynamics of the fluid by the linearized Navier-Stokes equations. We verify our simulation scheme by means of a Chapman-Enskog expansion. Our method is applied to ...
The Enskog–Vlasov equation is a phenomenological kinetic that extends the Enskog for dense (non-ideal) hard-sphere fluid by adding an attractive soft potential tail to purely repulsive contribution. Simplifying assumptions about pair correlations lead Vlasov-like self-consistent force field adds non-local collision integral. Within limitations imposed underlying assumptions, extension gives abi...
the strength of concrete is a function of the proportions of the constituent materials, namely, cement, water, fine and coarse aggregates. the conventional methods used to determine the mix proportions that will yield the desired strength, are laborious, time consuming and expensive. in this paper, a mathematical method based on modified regression theory is formulated for the prediction of con...
