Introduction: Chemical interactions between Venus’ atmosphere and surface rocks may be crucial to understanding the atmosphere’s composition [1-3], and to interpreting surface geology and physical properties [2,4,5]. Most studies have emphasized the atmosphere – its composition and ‘chemical sediments,’ and few have focused on what happens to basalts and their minerals in reaction with the atmo...

We propose a new single-step mechanism for the combustion of arbitrary hydrocarbons and alcohols. Unlike most models, no tabulation is required, as method builds upon analytical description thermochemical equilibrium fuel-oxidizer mixtures including dihydrogen carbon monoxide – two species usually discarded in one-step descriptions yielding correct adiabatic temperature. The chemistry includes ...

We propose a novel strategy for the accurate determination of non-uniform thermochemical distributions in axisymmetric flames using line-of-sight laser absorption spectroscopy with constraints hybrid information. In this method, computational fluid dynamics (CFD) simulation or other diagnostic method (e.g., thermocouple measurement) is used to qualitatively characterize properties, whereas kine...

Controlling inclusion content in high chromium steel is very important to prevent submerged entry nozzle from clogging continuous casting and avoid the negative impacts of inclusions on properties. Therefore, effects temperature elements phase stability diagram should be clarified bearing steel. However, effect boundaries MgO, MgO∙Al2O3 Al2O3 are much different among researchers. The direction ...

We present the open-source pyratbay framework for exoplanet atmospheric modeling, spectral synthesis, and Bayesian retrieval. The modular design of code allows users to generate 1D parametric models temperature, abundances (in thermochemical equilibrium or constant-with-altitude), altitude profiles in hydrostatic equilibrium; sample ExoMol HITRAN line-by-line cross sections with custom resolvin...

The development of tools for the synthesis, design, and optimization biorefineries requires deep knowledge thermochemical processes involved in these schemes. For this project, three models from scientific literature were implemented to simulate processes: fast pyrolysis a fluidized bed, fixed-bed, fluidized-bed gasification using Aspen PlusTM software. These allow user obtain performance, cons...
