Chia-Yu Hsieh, Tai-Chia Lin, Chun Liu, Pei Liu

摘要:

在本文中,我们考虑一个非等温电动力学模型,这是从能量变分方法。电荷输运过程由变温Poisson-Nernst-Planck方程描述,热通量满足傅里叶定律。该Poisson-Nernst-Planck-Fourier模型既满足热力学第一定律和第二定律,又满足Onsager互逆关系,因而是热力学相容的。最后,在初始数据较小的假设下,利用能量方法证明了该模型的整体适定性。

英文摘要:

In this paper, we consider a non-isothermal electrokinetic model, which is derived from the Energetic Variational Approach. The charge transport is described through the Poisson-Nernst-Planck equations with variable temperature, and the heat flux satisfies the Fourier's law. This Poisson-Nernst-Planck-Fourier model satisfies both the first law and second law of thermodynamics as well as the Onsager's reciprocal relations, thus it is thermodynamic-consistent. Finally, we prove the global well-posedness for this model under the smallness assumption of the initial data by the energy method.
