Plato : A High-Fidelity Library for Multicomponent Gases and Plasmas

This work presents plato (PLAsmas in Thermodynamic nOn-equilibrium), a high-fidelity library for the thermodynamics, transport, and collisional-radiative kinetics of equilibrium and nonequilibrium multicomponent gases and plasmas. plato is implemented in a modular and extensible fashion using Fortran 2003/2008 and can also be utilized in C and C++ codes. The theoretical framework of the library is based on nonequilibrium kinetic theory for dilute gases. A distinctive feature of plato is the availability of a hierarchy of physicochemical models of increasing complexity and accuracy, ranging from legacy multitemperature to grouping and/or collisional-radiative models. Application examples are presented and discussed to demonstrate the main features and capabilities of the library.
