The purpose of a plasma chemistry model is prediction of chemical species densities, including understanding the mechanisms by which such species are formed. These aims are compromised by an uncertain knowledge of the rate constants included in the model, which directly causes uncertainty in the model predictions. We recently showed that this predictive uncertainty can be large—a factor of ten ...
In the last year or so, a number of new open-access titles have been launched or established journals flipped to an “author pay” model, dramatically changing the open-access publishing landscape within chemistry. It is worth noting that when ChemistryOpen began in 2011, it was the first open-access society-owned general chemistry journal. Since it started, ChemistryOpen has grown steadily, main...
Saeed Baghery was born in Amol/Mazandaran (Iran) in 1985. He completed his B.Sc. in Pure chemistry in 2009 from Islamic Azad University of Amol, Mazandaran, Iran. He was graduated from M.Sc. degree under the supervision of Dr. Seyed Mohammad Vahdat in Organic Chemistry from Islamic Azad University of Amol, Mazandaran, Iran. He is currently Organic Chemistry Ph.D student under the supervision of...
The Smagorinsky and One-Equation sub-grid scales (SGS) for modeling of large scale pool fire using Large Eddy Simulation (LES) has been used and compared. The fire heat release rate was 2.07 MWatt and the fuel was Methane. Based on the mixture fraction approach and infinity fast chemistry assumption, the mean velocity profile and turbulence kinetic energy are calculated and compared against exp...
[1] We present an evaluation of a nested high‐resolution Goddard Earth Observing System (GEOS)‐Chem chemistry transport model simulation of tropospheric chemistry over tropical South America. The model has been constrained with two isoprene emission inventories: (1) the canopy‐scale Model of Emissions of Gases and Aerosols from Nature (MEGAN) and (2) a leaf‐scale algorithm coupled to the Lund‐P...
We present a comprehensive description and benchmark evaluation of the tropospheric chemistry version of the global chemistry transport model TM5 (Tracer Model 5, version TM5-chem-v3.0). A full description is given concerning the photochemical mechanism, the interaction with aerosol, the treatment of the stratosphere, the wet and dry deposition parameterizations, and the applied emissions. We e...
In addition to theory and experiment, simulation of reacting flows has become important in policymaking, industry, and combustion science. However, simulations of reacting flows can be extremely computationally demanding due to the wide range of length scales involved in turbulence, the wide range of time scales involved in chemical reactions, and the large number of species in detailed chemica...
