Numerical Solution of Hard Rock Disintegration
This paper focuses on a numerical analysis of a hard rock (ore) disintegration process. A bit moves into the ore and subsequently disintegrates it. The disintegration (i.e. fracture of ore) is solved via a deterministic approach (FEM) and a probabilistic approach (FEM in combination with the SBRA Simulation-Based Reliability Assessment method, i.e. Monte Carlo simulations, stochastic inputs). T...
متن کاملElusiveness of fluid-fluid demixing in additive hard-core mixtures.
The conjecture that when an additive hard-core mixture phase separates when one of the phases is spatially ordered, well supported by considerable evidence, is in contradiction with some simulations of a binary mixture of hard cubes on cubic lattices. By extending Rosenfeld's fundamental measure theory to lattice models we show that the phase behavior of this mixture is far more complex than si...
متن کاملEntropy-driven demixing in binary hard-core mixtures: From hard spherocylinders towards hard spheres
We present a computer simulation study of a binary mixture of hard spherocylinders with different diameters (D1,D2) and the same lengths (L15L25L). We first study a mixture of spherocylinders with lengths L 515D2 and D150, which can be regarded as a mixture of rodlike colloids and ideal needles. We find clearly an entropy-driven isotropic-isotropic (I-I) demixing transition in this mixture. In ...
متن کاملPhase separation in binary hard-core mixtures: An exact result.
We show that certain lattice models for a binary mixture of hard particle mixtures can be mapped onto a one-component lattice gas or, equivalently, onto an Ising model. The repulsive interaction between unlike particles in the mixture leads to an attractive nearest-neighbour interaction in the one-component lattice gas. In particular, we have found a lattice model of a binary hard-core mixture ...
متن کاملEntropic interfaces in hard-core model amphiphilic mixtures.
We investigate bulk and interfacial properties of a recently proposed hard-body model for a ternary mixture of amphiphilic particles, spheres and needles using density functional theory. The simple model amphiphiles are formed by bonding a vanishingly thin needle tail radially to a hard-sphere head group. Such particles provide a natural amphiphile when added to a binary mixture of spheres and ...
