We generalize the BGK model proposed in Bisi and C谩ceres (2016) to a mixture constituted by both monoatomic and polyatomic gas species with each polyatomic one being characterized by its own number of discrete internal energy levels, to model its non-translational degrees of freedom. We prove...
Kinetic models for polyatomic gases have two temperatures for the two different types of degrees of freedom, the translational and the internal energy degrees of freedom. Therefore, in the case of BGK models one expects two types of relaxations, a relaxation of the distribution function to a Maxw...

First, we obtain the approximate transport equation for the given kinetic models of BGK type. Then using the averaging lemma, we obtain the convergence. This paper shows how to relate the given kinetic model with the averaging lemma to get the convergence....
We consider the Bathnagar–Gross–Krook (BGK) model, an approximation of the Boltzmann equation, describing the time evolution of a single momoatomic rarefied gas and satisfying the same two main properties (conservation properties and entropy inequality

AF:辅助进位标志,如果当进行加法运算时,第三位向第四位进位,或者进行减法运算时,第三位从第四位借位,则AF为1。辅助进位标志一般在BCD码运算中作为是否进行十进制调整的判断依据。 OF:溢出标志,运算结果产生溢出则为1,否则为0。反馈 收藏

The Hilbert method is applied to the Bhatnagar-Gross-Krook (BGK) model kinetic equation with a velocity dependent collision frequency; we consider the so-called VHP interaction. The pressure tensor and heat flux vector are evaluated to the Navier-Stokes hydrodynamic order.doi:10.1080/00268978800100351...
If I had a car of my own, I()it to your sister yesterday. A. will lend B. would lend C. should lend D. would have lent 相关知识点: 试题来源: 解析 D [解析] 句子的大意为:如果我自己有车,昨天我就借给你妹妹了。此句为虚拟语气,与过去事实相反,所以D项符合题意。
