An Exact-Steady-state Adaptive Chemistry method for combustion simulations: Combining the efficiency of reduced models and the accuracy of the full model

Combustion and Flame, 2012
Abstract Many reduced-model methods have been developed to alleviate the computational expense of simulating chemically reacting flows with detailed kinetics. However, it is still impossible to determine exactly the loss in accuracy relative to the full model when reduced kinetic models are used for predicting quantities of interest (typically state ...

Chemical reduction of sulphur dioxide to free sulphur with lignite and coal. 1. Steady-state reaction chemistry and interaction of volatile components

Fuel, 1980
Abstract The chemical reduction of SO2 with North Dakota lignite has been discovered to be a facile reaction which occurs at a relatively low temperature of 600–650 °C. Under optimum conditions, the reaction chemistry can be controlled to allow 85–90% conversion of SO2 to free sulphur in a single-stage reaction.

A coupled one‐dimensional radiative‐convective, chemistry‐transport model of the atmosphere: 1. Model structure and steady state perturbation calculations

Journal of Geophysical Research: Atmospheres, 1985
An atmosphere model composed of a narrow band radiative‐convective (RC) code coupled with a one‐dimensional chemistry and transport code is described. The RC model, formulated in log‐pressure coordinates, includes accurate solar absorption calculations for O3, O2, H2O, and CO2.

Integrated Production Chemistry Management Of The Schoonebeek Heavy Oil Redevelopment in the Netherlands: From Project to Start-Up and Steady State Production

SPE Heavy Oil Conference Canada, 2012
Abstract This paper describes the production chemistry management process undertaken during the design, commissioning and start-up phases of the Schoonebeek redevelopment. Challenging separation issues, saline water, together with a multitude of other process conditions, resulted in complex, but robust application portfolio.

Difference equation solutions for non-steady-state diffusion of charged particles in solids

Solid State Communications, 1974
Abstract The hopping transport of charged particles through a solid is described by means of difference equations based on the concept of classical thermal motion over discrete energy barriers. Homogeneous electric fields and concentration gradients are considered to be the driving forces for transport. Transient and steady-state currents are derived,
