    ABSTRACT: The sedimentation of a heavy elliptical particle in a two-dimensional channel filled with Newtonian fluid under oscillatory pressure driven flow has been numerically investigated by using the finite element arbitrary Lagrangian–Eulerian method. The effects of particle Reynolds number, initial position, blockage ratio, as well as oscillation frequency and amplitude on the flow patterns during sedimentation have been studied. The results show that there exists an equilibrium position for high frequency flow, and the position of the heavier particle is closer to the centerline. As rotation contributes to non-uniform pressure on particle surface, the further initial position and lower amplitude lead to the larger scale zigzag migration; however, the maximum lateral displacements of these low frequency zigzag motions are nearly the same due to the consistent lubrication limit. Moreover, our simulation results indicate that there are five distinct modes of settling in oscillatory flow: horizontal with offset, oscillating, tumbling throughout channel, tumbling at one side and the special ‘resonance’ phenomenon. The ‘resonance’ induced by the wall is shown to have a close association with the harmonious change of drag and lift on particle surface, and be sensitive to the oscillation in the wake and the periodic discharge of vorticity from behind the body.

    ABSTRACT: Surface waves in a square container due to its resonant horizontal elliptic or linear motion are investigated theoretically. The motion of the container is characterized by the ratio, expressed as tan Φ, of the length of the minor axis to the length of the major axis of its elliptic orbit, and by the angle θ between the directions of the major axis and one of its sidewalls. Using the reductive perturbation method, non-linear time evolution equations for the complex amplitudes of two degenerate modes excited by this motion are derived with the inclusion of linear damping. When tan Φ is small, for any θ these equations have two kinds of stable stationary solutions corresponding to regular co-rotating waves whose direction of rotation is the same as that of the container and regular counter-rotating waves of the opposite direction of rotation. As tan Φ increases to one, the region of forcing frequency in which stable regular counter-rotating waves are observed shrinks and then disappears for any θ. Solutions with chaotic or periodic slow variations in amplitude and phase of excited surface waves are also obtained for forcing frequencies where no stable stationary solutions exist. Non-stationary solutions are either unidirectionally or bidirectionally rotating waves. For θ = 0°, chaotic waves and bidirectionally rotating waves are observed more frequently for smaller tan Φ. For θ = Φ = 0°, for sufficiently small fluid depth, regular non-rotating waves are expected to occur for any forcing frequency. Moreover, stable stationary and non-stationary solutions obtained for Φ = 0° are found to agree fairly well with the experimental results in a preceding study. © 2015 The Japan Society of Fluid Mechanics and IOP Publishing Ltd.

    ABSTRACT: In this paper we have investigated the boundary layer analysis of an unsteady separated stagnation-point (USSP) flow of an incompressible viscous fluid over a flat plate, moving in its own plane with a given speed . The effects of the accelerating parameter a and unsteadiness parameter β on the flow characteristics are explored numerically. Our analysis, based on the similarity solution of the boundary layer equations, indicates that the governing ordinary differential equation, which is non-linear in nature, has either a unique solution, dual solutions or multiple solutions under a negative unsteadiness parameter β with a given value of a. Whatever the number of solutions may be, these solutions are of two types: one is the attached flow solution (AFS) and the other is the reverse flow solution (RFS). A novel result which emerges from our analysis is the relationship between a and β. This relationship essentially gives us the conditions needed for the solutions that exhibit flow separation (where ) and those conditions that exhibit only flow reattachment (where ). Another noteworthy result which arises from the present analysis is the existing number of non-zero stagnation-points inside the flow for the given values of a and β. It is found that this number is exactly two when the velocity gradient at the wall is positive; otherwise this number will only be one. For a stationary plate , this USSP flow is found to be separated for all values of a and β in both cases of AFS and RFS. Finally, we have also established that in the case of AFS flow over a stationary plate, no stagnation-point exists inside the flow, even though the flow becomes separated for all values of a and β.
