Global weak solution to the inhomogeneous Navier–Stokes–Vlasov equations

Abstract: The inhomogeneous Navier-Stokes-Vlasov equations for fluid-particle flows are considered in the threedimensional space. The coupling in the fluid-particle system arises from the drag force in the fluid equations and the acceleration in the Vlasov equation. An initial-boundary value problem is studied in a bounded domain with large initial data. The existence of global weak solution is established through an approximation scheme, a fixed point argument, energy estimates, and a weak convergence method.

“…Thanks to (3.39) 2 and (3.40), the Aubin-Lions Lemma, u m = S(ũ) is compact in A. On the other hand, it is easy to verify that S is sequentially continuous, see [9,12] for the details. Thus Schauder's fixed point theorem gives that S has a fixed point u m in A.…”

“…The first work in this field was [8] where the author proved the global existence of weak solution and their largetime behavior for the Vlasov-Stokes equations. The existence theorem for weak solutions was extended in [1,3,10,12,13], where the authors did not neglect the convection term and considered the Navier-Stokes equations, including incompressible and compressible ones. In [5], the existence and uniqueness of global smooth solutions near an equilibrium was proved under smallness conditions for the Navier-Stokes system coupled with the Vlasov-Fokker-Planck equation in 3D.…”

“…To be more precise, we can not extract the desired dissipation rate of the density in D. On the other hand, if we consider the pressureless viscous fluid [25] or inhomogeneous fluid [14,27] instead of the compressible Navier-Stokes equations, we can show that the exponential alignment between particles and fluid velocities by using the Lyapunov functional L and the energy functional E without the terms related to the pressure. In fact, the lemma below shows the Lyapunov functional L is bounded by sum of the dissipation D and that term related to the pressure from above.…”

“…Some of the previous works on the existence theory for the coupled kinetic-fluid equations can be summarized as follows. The first result on the weak solutions to the Vlasov-Stokes equations is performed in [21], and later this work is extended to the Vlasov-Navier-Stokes equations in [1,7,16,27,29]. With a diffusion term in the Vlasov equation, i.e., VlasovFokker-Planck equations, there are a number of literature on the global existence of weak and strong solutions for the interactions with homogeneous or inhomogeneous fluids [2,5,9,10,11,12,17,23].…”

“…Existence for fluid-kinetic systems is nowadays well-understood, and there is no exception for the Vlasov-Navier-Stokes system: global weak solutions are known to exist for periodic boundary conditions ( [5]), bounded domains with various boundary condition ( [21,20]) or even moving domains ( [7]) and if the initial data is small enough, the system is well-posed in a narrower set of solutions ( [11,18]). In contrast, the uniqueness issue has not been very much studied.…”
