In this work, a study involving the fully coupled Euler and Navier-Stokes reactive equations is performed. These equations, in conservative finite volume contexts, employing structured spatial discretization, on condition of thermochemical non-equilibrium, are analyzed. High-order studies accomplished using Spectral method Streett, Zang, Hussaini. The high enthalpy hypersonic flows around circu...

Ceramic/metal interfaces occur in a great number of important applications, such as ceramic/metal composites, microelectronics packaging, ceramic/metal seals, and so forth. Understanding the formation and evolution of such interfaces is therefore essential for the better design and optimization of these technologies. In this thesis, a methodology for the study of the thermochemical interactions...

A general feature of both isochemical and thermochemical studies of mantle convection is that horizontal plume velocities tend to be smaller than typical convective velocities, however, it is not clear which system leads to a greater fixity of mantle plumes. We perform twoand three-dimensional numerical calculations and compare both thermochemical and isochemical cases with similar convective v...

This paper focuses on the study of a solid/gas thermochemical reaction between a porous reactive bed and vapor. The objective is to determine the operating mode, either closed or open system, that best suits the requirements of a thermochemical seasonal storage applied to house heating. These two working modes have been compared thanks to two validated 2D models. This study shows that for the c...

Acid-base thermochemistry of isolated amino acids containing oxygen or sulfur in their side chain (serine, threonine, cysteine and methionine) have been examined by quantum chemical computations. Density functional theory (DFT) was used, with B3LYP, B97-D and M06-2X functionals using the 6-31+G(d,p) basis set for geometry optimizations and the larger 6-311++G(3df,2p) basis set for energy comput...
