چکیده

We use a boolean cellular automaton model to describe the diffusion limited dynamics of the irreversible reaction A+A → A+ S on a 1D lattice. We derive a set of equations for the dynamics of the empty interval probabilities from which explicit expressions for the particle concentration and the two point correlation can be obtained. It is shown that the long time dynamics is in agreement with the off-lattice solution. The early time behavior, however, predicts a slower decay of the concentration.

Molecular Dynamics Simulation of Al/NiO Thermite Reaction Using Reactive Force Field (ReaxFF)

In this work, the thermal reaction of aluminum (Al) and nickel oxide (NiO) was investigated by molecular dynamics simulations. Some effective features of reaction such as reaction temperature, the reaction mechanism, and diffusion rate of oxygen into aluminum structure were studied. ReaxFF force field was performed to study the Al/NiO thermite reaction behavior at five different temperatures (5...

Effects of thermal diffusion and chemical reaction on MHD transient free convection flow past a porous vertical plate with radiation, temperature gradient dependent heat source in slip flow regime

An analytical investigation is conducted to study the unsteady free convection heat and mass transfer flow through a non-homogeneous porous medium with variable permeability bounded by an infinite porous vertical plate in slip flow regime while taking into account the thermal radiation, chemical reaction, the Soret number, and temperature gradient dependent heat source. The flow is considered u...

Dynamic Behavior of an Oil Droplet Adhered to the Wall Surface in a Channel Flow by the Lattice Boltzmann Method

The Lattice Boltzmann Method is used to simulate the dynamics of droplet deformation in a channel flow under various conditions. The droplet behavior has been investigated under transient conditions. For cases where the droplet remains attached to the surface, the shape deformation of the droplet during crawling is captured. It has been shown that there is a limiting value for the droplet volum...

Reaction Dynamics of NH2+OH on an Interpolated Potential Energy Surface

QCT calculations were performed to study the behavior of energized NH2OH formed by association collision of NH2 radical with OH radical. A potential energy surface that describes the behavior of the title reaction has been constructed by interpolation of ab initio data. H2O, HON, HNO, NH3, O, H2NO, cis or trans-HONH, and H products and two vibrationally energized NH2OH and NH3O adducts were obs...
