TL;DR: In this article, the authors present an exhaustive overview of the main experimental papers dealing with underexpanded jets, from those where there is clearly a lack of confidence, and some clues are given on the numerical methods that may be used if one wants to study such jets numerically, together with an emphasis on the specific thermodynamic difficulties associated to this kind of extreme conditions.

TL;DR: The present Lagrangian numerical scheme thus combines Riemann solvers and artificial heat exchanges and is validated against exact solutions based on the multiphase shock relations as well as exact solutions of the Euler equations in the context of interface problems.

TL;DR: In this paper, the phase change materials (PCM) are placed in the heat transfer fluid solar loop from the domestic hot water (SDHW) system, and a genetic algorithm is used to propose an optimized system configuration.

TL;DR: In this paper, a hyperbolic multiphase flow model with a single pressure and a single velocity but several temperatures is proposed to deal with the detonation dynamics of condensed energetic materials.

TL;DR: A new projection method is developed for the Euler equations to determine the thermodynamic state in computational cells that is very robust, accurate, oscillation free and conservative and extended to the numerical approximation of a non-conservative hyperbolic multiphase flow model for interface computation and shock propagation into mixtures.
