我们考虑离子在流体中的电扩散,描述的能斯特-普朗克-Navier-Stokes系统。我们证明了在以下情况下,在三维空间中具有光滑边界的有界域中,对于任意光滑数据,系统具有全局光滑解。我们认为:一个任意正的Dirichlet边界条件的离子浓度,任意Dirichlet边界条件的潜力,任意正的初始浓度,和任意规则的无发散初速度。全局正则性保持任何积极的,可能不同的扩散率的离子,在两个离子物种的情况下,耦合到斯托克斯方程的流体。在Navier-Stokes耦合的情况下,如果速度是正则的,结果也成立。同样的整体光滑的解决方案被证明持有任意多的离子物种,以及,但在这种情况下,我们需要他们所有的扩散率相同。
We consider ionic electrodiffusion in fluids, described by the Nernst–Planck–Navier–Stokes system. We prove that the system has global smooth solutions for arbitrary smooth data in bounded domains with a smooth boundary in three space dimensions, in the following situations. We consider: a arbitrary positive Dirichlet boundary conditions for the ionic concentrations, arbitrary Dirichlet boundary conditions for the potential, arbitrary positive initial concentrations, and arbitrary regular divergence-free initial velocities. Global regularity holds for any positive, possibly different diffusivities of the ions, in the case of two ionic species, coupled to Stokes equations for the fluid. The result also holds in the case of Navier–Stokes coupling, if the velocity is regular. The same global smoothness of solutions is proved to hold for arbitrarily many ionic species as well, but in that case we require all their diffusivities to be the same.
