Chemical reaction rate and diffusion rate
Chemical reaction rate and diffusion rate were defined. The concomitant advances in theory, measuring systems and computer simulation bring the new perspectives to the chemical reaction with diffusion studying. The obtained results shows effect the chemical reaction rate and diffusion. The obtained results demonstrate characterization of the dynamic and steady state conditions of the chemical s...
متن کاملPreferential Diffusion Effects on the Burning Rate of Interacting Turbulent Premixed Hydrogen-Air Flames
The upstream interaction of twin premixed hydrogen-air flames in 2-D turbulence is studied using direct numerical simulations with detailed chemistry. The primary objective is to determine the effect of flame stretch on the overall burning rate during various stages of the interaction. Preferential diffusion effects are accounted for by varying the equivalence ratio from symmetric rich-rich to ...
متن کاملModeling soot formation in turbulent kerosene/air jet diffusion flames
Soot volume fraction and number density in a turbulent diffusion flame burning kerosene/air were predicted using two approaches. The first used a conventional soot inception model based on the acetylene concentration and is referred to as the acetylene model. The second used a soot inception model based on the formation rate of three and two ring aromatics [1] and is referred to as the PAH ince...
متن کاملModeling and Solution of Methane Jet Diffusion Flames
The aim of this work is to model a jet diffusion flame, to show the corresponding proof of existence of solutions, and to present numerical results. The model is based on the flamelet equations for the chemistry and on the mixture fraction for the flow. Numerical tests are carried out for Sandia Flame D and the results are found to compare well with available data found in the literature.
متن کاملReaction-diffusion with a time-dependent reaction rate: the single-species diffusion-annihilation process
We study the single-species diffusion-annihilation process with a time-dependent reaction rate, λ(t) = λ0 t−ω . Scaling arguments show that there is a critical value of the decay exponent ωc(d) separating a reaction-limited regime for ω > ωc from a diffusion-limited regime for ω < ωc. The particle density displays a mean-field, ω-dependent, decay when the process is reaction-limited whereas it ...
