In an early approach, a kinetic model with multiple translational temperature [K. Xu, H. Liu and J. Jiang, Phys. Fluids 19, 016101 (2007)] to simulate non-equilibrium flows was proposed. In this paper, instead of using three temperatures in the -directions, we define the translational ...

The most physically consistent approach to model non-equilibrium flows relies on the direct numerical solution of the master equation5,6,9,10,11,12,13, whereby all the relevant spatial and temporal scales resulting from chemical and radiative processes are accounted for. Indeed, the availability of...
In this study, the hypersonic non-equilibrium flows over spheres are numerically investigated by a robust conservation element and solution element (CE/SE)... H Shen,C Wen,HS Massimi 被引量: 0发表: 2014年 The equilibrium flux method for the calculation of flows with non-equilibrium chemical ...
Thirteen turbulence models have been assessed in classical non-equilibrium flows. • Homogeneous shear flows have been shown to challenge turbulence models. • RST models return reasonable turbulence fields, but not always the mean flow fields. • All models were unable to predict the reattachmen...
Non-equilibrium flows of N 2/N and O 2/O mixtures with dissociation, recombination and excitation of vibrational levels are considered. Vibrational distributions, gas dynamic parameters as well as the transport coefficients and total energy flux are computed along the nozzle axis using four ...
This paper deals with violent discontinuities in shallow water flows with large Froude number F. On a horizontal base, the paradigm problem is that of the ... Carina M. Edwards S. D. Howison H. Ockendon and J. R. Ockendon - 《Ima Journal of Applied Mathematics》 被引量: 50发表: 2008...
In that particular case, this led to some later work on preferential flows (e.g., Watson and Luxmoore, 1986); in many other cases, such values were simply excluded as "outliers" or anomalies. Such was the power of the B-R paradigm....
Moment closures of gaskinetic theory offer a method for the prediction of non-equilibrium flows which have a wider range of validity than standard continuum methods, such as solution of the Navier-Stokes equa- tions, and can be much more computationally effi- cient than particle-based techniques...
SU2-NEMO, a recent extension of the open-source SU2 multiphysics suite’s set of physical models and code architecture, is presented with the aim of introducing its enhanced capabilities in addressing high-enthalpy and high-Mach number flows. This paper discusses the thermal nonequilibrium and fini...
