“…The mathematical model features a combination of conservative and dissipative properties as can be observed by the conservation of angular momentum (1.3) and the energy inequality (4.5). These are distinctive characteristics for this type of fluid-solid interactions (see also [5,17,8,18]). We prove the existence of weak solutions á la Leray-Hopf to (1.1) corresponding to initial data with arbitrary (finite) kinetic energy.…”

“…In contrast, there is a large literature dealing with the motion of fluid-filled rigid bodies with no-slip boundary conditions, it spans from the early work by Stokes [38], Zhukovskii [42], Hough [11], Poincaré [26], and Sobolev [35] to more recent contributions mostly concerned with stability problems ( [32,33,21,4,15,13,12,34,16,9,5,17]). A comprehensive study of the motion of fluid-filled rigid bodies has recently been given in [8] (in an L 2 framework), and in [18] (in a more general L q framework). It is shown that equilibria correspond to permanent rotations (rotations with constant angular velocity around the central axes of inertia) of S with the fluid at a relative rest with respect to the solid.…”

We consider the inertial motion of a system constituted by a rigid body with an interior cavity entirely filled with a viscous incompressible fluid. Navier boundary conditions are imposed on the cavity surface. We prove the existence of weak solutions and determine the critical spaces for the governing evolution equation. Using parabolic regularization in time-weighted spaces, we establish regularity of solutions and their long-time behavior. We show that every weak solution à la Leray-Hopf to the equations of motion converges to an equilibrium at an exponential rate in the Lq-topology for every fluid-solid configuration.A nonlinear stability analysis shows that equilibria associated with the largest moment of inertia are asymptotically (exponentially) stable, whereas all other equilibria are normally hyperbolic and unstable in an appropriate topology.

“…However, it is only over the past few years, that a rigorous mathematical analysis has been initiated, with the objective of investigating a fundamental property of such coupled systems, namely, the characterization of their "ultimate dynamics" [24,11,5,12,15,9,14,21]. In fact, as shown by both experiment and qualitative analysis [27,3,4], the viscous liquid acts as a damper on the rigid body to the point, in some cases, of even bringing it to rest (see [13,15] for a rigorous mathematical explanation).…”

“…More recently, the present authors have started to investigate the problem of a rigid body with a fluid-filled interior cavity by relaxing the assumption of incompressibility and, as in [11,5,9], performed their analysis in the case of inertial motions. Their main achievement was to show that, under suitable hypotheses on the "mass distribution" and for "small" Mach numbers, the system will eventually tend to a steady-state characterized by a rigid, uniform rotation around one of the central axes of inertia [10].…”

However, unlike [11,5,9], the analysis in [10] is carried out in the class of strong solutions, whose existence is established for initial data that are smooth enough and Here r, p and w are fluid density, pressure and velocity fields, ̟ is the angular velocity of B, and η the velocity of its center of mass C. Moreover, y C denotes the vector position of C, while…”

We prove the existence of a weak solution to the equations describing the inertial motions of a coupled system constituted by a rigid body containing a viscous compressible fluid. We then provide a weak-strong uniqueness result that allows us to completely characterize, under certain physical assumptions, the asymptotic behavior in time of the weak solution corresponding to smooth data of restricted "size," and show that it tends to a uniquely determined steady-state. 2"small" in size. As explained in the introductory section in [10] the analogous study in the larger class of weak solution corresponding to data possessing just finite energy appears, currently, out of reach. The main reason is ascribed to the fact that a necessarily detailed study of the Ω-limit requires that weak solutions become eventually smooth enough, a property that, while true in the incompressible case [5], need not be generally valid if the fluid is compressible [16].This drawback notwithstanding, one may wonder if, at least, a weak solution with smooth and sufficiently "small" initial data could satisfy the above property. The latter is certainly true, if one can show a weak-strong uniqueness result, which would, in particular, ensure that the weak solution is strong for all positive times.Objective of this article is to prove that this is, in fact, the case. More precisely, we show that, for generic initial data with finite energy, there corresponds at least one weak solution (see Theorem 3.2) suitably defined (see Definition 3). Furthermore, we show that if there is a strong solution (also suitably defined) possessing the same data, then necessarily it should coincide with the weak one (see Theorem 5.2). In view of this result, we may then conclude that, for smooth and "small" initial data, the weak solution must coincide with that constructed and used in [10], and this will ensure that, as established in [10], under the assumption of suitable "mass distribution" and "small" Mach numbers, the ultimate state reached by the weak solution must be a uniform rotation around a central axis of inertia.The plan of the paper is the following. In Section 2 we give a formulation of the problem and recall the relevant equations. Section 3 is dedicated to the definition of weak solutions and the proof of their existence (Theorem 3.2). In achieving the latter, we appropriately adjust to the case at hand an approximation procedure developed in [23,6]. Successively, in Section 4, we state results of local and global existence and uniqueness of strong solutions proved in [10]; see Theorems 4.1 and 4.2. The following Section 5 is devoted to the proof that the weak and the strong solution, dealt with before, corresponding to the same data must, in fact, coincide; see Theorem 5.2. In the proof of this result, we adapt the arguments of [7,18,2]; see also [18]. Once the weak-strong coincidence has been established, we dedicate the last two sections to recall and formulate the results proved in [10] concerning the asymptotic behavior of a strong solution for...

We consider the inertial motion of a rigid body with an interior cavity that is completely filled with a viscous incompressible fluid. The equilibria of the system are characterized and their stability properties are analyzed. It is shown that equilibria associated with the largest moment of inertia are normally stable, while all other equilibria are normally hyperbolic.We show that every Leray-Hopf weak solution converges to an equilibrium at an exponential rate. In addition, we determine the critical spaces for the governing evolution equation, and we demonstrate how parabolic regularization in time-weighted spaces affords great flexibility in establishing regularity of solutions and their convergence to equilibria.2010 Mathematics Subject Classification.
