Scalar Mixing and Chemical Reaction Simulations Using Lattice Boltzmann Method
We simulate scalar mixing and chemical reactions using the lattice Boltzmann method. Simulations of initially non-premixed binary mixtures yield scalar probability distribution functions that are in good agreement with direct numerical simulation (of NavierStokes equation) data. One-dimensional chemically-reacting ow simulation of a premixed mixture yields a ame speed that is consistent with ex...
متن کاملDevelopment of Coupled Flowfield - Radiation Solution Methods in Ablative Environments
A seven-species hypersonic flow solver that independently tracks vibrational energies of diatomic species has been coupled with SPRADIAN for the purposes of developing a spectrally accurate coupled radiation / flowfield solution. Results are presented for the FIRE-II and RAM-C geometries, and compared to experiment results where available. Shortfalls of the method are identified, along with ave...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Homogenization induced by chaotic mixing and diffusion in an oscillatory chemical reaction.
A model for an imperfectly mixed batch reactor with the chlorine dioxide-iodine-malonic acid (CDIMA) reaction, with the mixing being modelled by chaotic advection, is considered. The reactor is assumed to be operating in oscillatory mode and the way in which an initial spatial perturbation becomes homogenized is examined. When the kinetics are such that the only stable homogeneous state is osci...
متن کاملMixing and reaction efficiency in closed domains.
We present a numerical study of mixing and reaction efficiency in closed domains. In particular, we focus our attention on laminar flows. In the case of inert transport the mixing properties of the flows strongly depend on the details of the Lagrangian transport. We also study the reaction efficiency. Starting with a little spot of product, we compute the time needed to complete the reaction in...
