Calculating thermochemical equilibrium for multiphysics simulations of nuclear materials : development of yellowjacket gibbs energy minimiser
… has been an increasing interest in incorporating equilibrium thermodynamics calculations in multi-physics frameworks such as the Multiphysics Object Oriented Simulation Environment (MOOSE). To simulate corrosion in molten salt reactors, a new MOOSE-based tool named Yellowjacket has been developed …

Observations, Thermochemical Calculations, and Modeling of Exoplanetary Atmospheres
… planets through observing, performing thermochemical calculations, and modeling their atmospheres. We used Spitzer multi-wavelength secondary-eclipse observations to characterize planetary atmospheres. We chose targets with high signal-to-noise ratios, as their deep eclipses allow us to …

Characterizing Exoplanet Atmospheres: From Light-curve Observations to Radiative-Transfer Modeling
… exoplanet atmospheres. BART combines a thermochemical-equilibrium code, a one-dimensional line-by-line radiative-transfer code, and the Multi-core Markov-chain Monte Carlo statistical module to constrains the atmospheric temperature and chemical-abundance profiles of exoplanets. I …

Modeling Arsenic, Antimony, And Selenium Partitioning During Coal Combustion
… exclusions</p> <p>By rigorously accounting for thermochemical equilibrium, kinetics, and transport experienced by the various associated forms of trace elements inside the coal, this developed model can be used to visualize aspects related to trace element release from pyritic family mineral …

The Atmospheric Fingerprints of Volcanism: Simulating Volcanic Outgassing and Secondary Atmospheres on Rocky Planets
… above in order to be accurately modelled as in thermochemical equilibrium, with the reactions of key species (NH3, CO and CH4) being quenched over geological time below this point. Chapter 6 returns to the effect of hydrogen escape on volcanic atmospheres, exploring how escape modifies the …

Microanalytical Investigations of Presolar SiC Grains as Probes of Condensation Conditions in Astrophysical Environments
… in the same SiC grain, indicates that thermochemical equilibrium must have been maintained over a wide range of temperatures during SiC grain condensation. I observed that SiC crystal domain size varies with stellar source, presumably as a result of the very different growth conditions …

New Avenues in Atmospheric Modelling of Exoplanets
… the Feautrier method and radiative-convective equilibrium through the Rybicki Complete Linearisation method in a plane parallel atmosphere. This model allows for a detailed exploration of radiative processes and chemical compositions and their effects on observed emission spectra. I compared …
