Abstract
We consider the initial-boundary value problem of compressible Navier–Stokes–Vlasov equations under a local alignment regime in a one-dimensional bounded domain. Based on the relative entropy method and compactness argument, we prove that a weak solution of the initial-boundary value problem converges to a strong solution of the limiting two-phase fluid system. This work extends in some sense the previous work of Choi and Jung [Math. Models Methods Appl. Sci. 31(11), 2213–2295 (2021)], which considered the diffusive term ∂ ξξ f ɛ in the kinetic equation. Note that the diffusion term was not considered in this paper.
研究一维有界区域上局部对准区域下可压缩Navier-Stokes-Vlasov方程的初边值问题。基于相对熵法和紧性论证,证明了初始边值问题的弱解收敛于极限两相流体系统的强解。这项工作在某种意义上扩展了Choi和Jung之前的工作。模型、方法、应用。科学通报,31(11),2213-2295(2021)],考虑了动力学方程中的扩散项∂ξξ f /。请注意,本文没有考虑扩散项。
