This work presents a new formulation of the quantum-kinetic (QK) chemistry models, in
which the vibrational excitation is modeled with an anharmonic oscillator model. The new …

We generalize the BGK model proposed in Bisi and Cáceres (2016) to a mixture constituted
by both monoatomic and polyatomic gas species with each polyatomic one being …

Comprehensive quantum chemical analysis with the usage of the second-order perturbation
multireference XMCQDPT2 approach was carried out to study the processes in the+ H 2 …

This work quantifies the sensitivity of O 2+ O dissociation rates and relaxation to interatomic
potential energy surfaces at high-enthalpy, nonequilibrium flow conditions. State-to-state …

Following the reentry of the Intermediate eXperimental Vehicle in 2015, a lot of efforts were
carried out at the ONERA for the post-flight analysis and the reconstruction of the heat flux …

The simulation of the UV spectra of moderate Mach number flows is the strongest test
possible of the complex thermochemical models in hypersonic flows. To take advantage of …

The quantum kinetic chemical reaction model proposed by Bird for the direct simulation
Monte Carlo method is based on collision kinetics with no assumed Arrhenius-related …

A high fidelity internal energy relaxation model for N 2–N suitable for use in direct simulation
Monte Carlo (DSMC) modeling of chemically reacting flows is proposed. A novel two …

The modelling of aerothermodynamic flows is extremely challenging as it combines both
aerodynamics and thermodynamics disciplines. Aerothermodynamic applications typically …

Re-usable single stage to orbit launch vehicles promise to reduce the cost of access to
space, but their success will be particularly reliant on accurate modelling of their aero …
