Inhomogeneous Two-Species Annihilation in the Steady State
نویسنده
چکیده
A fundamental ingredient that controls the kinetics of the two-species annihilation process, A + B → 0, is the rate of reaction in the interfacial region between a domain of A’s and a domain of B’s. A natural way to study this interface is to prepare a system with initially separated components and then monitor the reaction rate as a function of time, as first studied by Gálfi and Rácz [1]. This type of geometry is also relatively more amenable to experimental investigation [2] than the more extensively studied case of a homogeneous, but random initial condition. In a mean-field description, the kinetics is described by the reaction-diffusion equations

Effects of differential mobility on biased diffusion of two species
Using simulations and a simple mean-field theory, we investigate jamming transitions in a two-species lattice gas under non-equilibrium steady-state conditions. The two types of particles diffuse with different mobilities on a square lattice, subject to an excluded volume constraint and biased in opposite directions. Varying filling fraction, differential mobility, and drive, we map out the pha...
متن کاملOptimal Pareto Parametric Analysis of Two Dimensional Steady-State Heat Conduction Problems by MLPG Method
Numerical solutions obtained by the Meshless Local Petrov-Galerkin (MLPG) method are presented for two dimensional steady-state heat conduction problems. The MLPG method is a truly meshless approach, and neither the nodal connectivity nor the background mesh is required for solving the initial-boundary-value problem. The penalty method is adopted to efficiently enforce the essential boundary co...
متن کاملThe Kinetics of Enzyme Mixtures
Even purified enzyme preparations are often heterogeneous. For example, preparations of aspartate aminotransferase or cytochrome oxidase can consist of several different forms of the enzyme. For this reason we consider how different the kinetics of the reactions catalysed by a mixture of forms of an enzyme must be to provide some indication of the characteristics of the species present. Based...
