多原子气体的二级本构理论:理论与应用

A second order constitutive theory for polyatomic gases: theory and applications

Anirudh Singh Rana, Sukratu Barve

摘要:

在经典的不可逆热力学(CIT)框架下,假设熵通量等于热流,得到了满足熵不等式的Navier-Stokes-Fourier(NSF)本构方程。这篇文章的重点是多原子气体的二阶本构方程的推导,它需要的基础上的CIT,但最重要的是,允许二次非线性的熵通量。

英文摘要:

In the classical irreversible thermodynamics (CIT) framework, the Navier Stokes Fourier (NSF) constitutive equations are obtained so as they satisfy the entropy inequality, by and large assuming that the entropy flux is equal to the heat flux over the temperature. This article is focused on the derivation of second-order constitutive equations for polyatomic gases; it takes the basis of CIT, but most importantly, allowing up to quadratic nonlinearities in the entropy flux.
