简化碰撞核相对论动力学方程的热通量
The heat flux from a relativistic kinetic equation with a simplified collision kernel
摘要:
我们展示了如何使用一个特殊的相对论性动力学方程与BGK类碰撞算子的热通量的随后的表达式可以铸造的形式所需的经典不可逆热力学。事实上,它与温度和数密度梯度线性相关,而不是所谓的“梯度理论中的一阶”所主张的加速度。在这里,我们明确地计算随后的输运系数,并与其他作者得到的结果进行比较。
英文摘要:
We show how using a special relativistic kinetic equation with a BGK- like collision operator the ensuing expression for the heat flux can be casted in the form required by Classical Irreversible Thermodynamics. Indeed, it is linearly related to the temperature and number density gradients and not to the acceleration as the so-called "first order in the gradients theories" contend. Here we calculate explicitly the ensuing transport coefficients and compare them with the results obtained by other authors.
