A finite-volume method is developed for simulating the mixing of turbulent flows at transcritical conditions and an entropy-stable formulation that combines high-order non-dissipative and low-order dissipative finite- volume schemes is proposed to preserve the physical realizability of numerical solutions across large density gradients.About:

An efficient lattice Boltzmann method for compressible aerodynamics on D3Q19 lattice
TL;DR: An efficient lattice Boltzmann model relying on a hybrid recursive regularization (HRR) collision operator on D3Q19 stencil is proposed for the simulation of three-dimensional high-speed compressible flows in both subsonic and supersonic regimes to reduce the complexity of correcting terms.

Nonadiabatic Flamelet Formulation for Predicting Wall Heat Transfer in Rocket Engines
TL;DR: In this article, a flamelet-based combustion model is proposed for the prediction of wall heat transfer in rocket engines and confined combustion systems to account for convective heat loss due to the interaction of the flamelet and the combustion medium.

Efficient Implementation of Weighted ENO Schemes
Guang-Shan Jiang,Chi-Wang Shu +1 more
TL;DR: A new way of measuring the smoothness of a numerical solution is proposed, emulating the idea of minimizing the total variation of the approximation, which results in a fifth-order WENO scheme for the caser= 3, instead of the fourth-order with the original smoothness measurement by Liuet al.
