Повний текст джерелаFluid flows play an important role in many natural phenomena as well as in many industrial applications. In this thesis, we are interested in oscillating flows origins from a Hopf bifurcation.The open shear-driven square cavity has two limit cycles separated by an unsteady quasi-periodic state. We have described this scenario in detail by using direct numerical simulations, linear stability analysis, and Floquet analysis. The Hopf bifurcation in Taylor-Couette flow gives rise to two solutions, spirals (traveling waves) and ribbons (standing waves in the axial direction). We discovered that the ribbons branch is followed by two consecutive heteroclinic cycles connecting two pairs of axisymmetric vortices. We studied in detail these two heteroclinic cycles.The linear stability analysis about the stationary solution is used to compute the threshold of the bifurcations. Another approach is the linearization about the mean field. This approach gives frequencies very close to that of the nonlinear system and shows in most cases a nearly zero growth rate. We have shown that spirals, ribbons, the lid-driven cavity and the flow around a prismatic object verify this property.In the thermosolutal convection, the frequencies obtained by the linearization about the mean field of the standing waves do not match the nonlinear frequencies and the growth rate is far from zero, on the other hand for the traveling waves this property is fully satisfied. We studied the validity of a self-consistent model in the case of the traveling waves. The self-consistent model consists of the mean field governing equation coupled with the linearized Navier-Stokes equation through the most unstable mode and the Reynolds stress term. This model calculates the mean field, the nonlinear frequency, and the amplitude without time integration. The self-consistent model is assumed to be valid for flows that satisfy the property of the mean field. We have shown that in this case, this model predicts the nonlinear frequency only very close to the threshold. We have improved significantly the predictions by considering higher orders in the Reynolds stress term

This paper presents a stability analysis of thin viscoelastic and micropolar liquid films flowing down a plate or cylinder moving in a vertical direction. The nonlinear rupture problem of thin micropolar liquid films on a cylinder is also investigated. The long-wave perturbation method is employed to derive the generalized nonlinear kinematic equations for a free film interface. The current thin liquid film stability analysis provides a valuable input to investigations into the influence of the style of motion of the vertical plate or cylinder on the stability behavior of the thin film flow. The normal mode method is employed to solve the linear solutions of the film flow, and the threshold conditions and linear growth rate of the amplitudes are obtained to analyze the linear stability behavior. This study utilizes the multiple scales method and derives the corresponding Ginzburg-Landau equation to characterize the nonlinear behavior of the flow. The subcritical stability, subcritical instability, supercritical stability, and supercritical instability states are obtained from the nonlinear stability analysis. The present rupture analysis of a thin liquid film on a cylinder supports investigations into the onset of film rupture and permits an understanding of the relative influences of factors such as micropolar parameter, cylinder radius, van der Waals potential, and surface tension on the rupture process. The following conclusions can be drawn from the current numerical modeling results: (1)Influence of style of motion of vertical plate or cylinder on stability behavior of thin film flow: A downward direction motion of the vertical plate or cylinder tends to enhance the stability of the downward-traveling film flow on the plate or cylinder. The film flow system becomes more stable as the downward direction velocity of the plate or cylinder increases. The effects of the viscoelastic parameter, , and the micropolar parameter, , on the stability of the thin film flow are diminished as the downward direction velocity of the plate or cylinder increases. Conversely, an upward direction motion of the plate or cylinder tends to reduce the stability of the down-traveling film flow. The film flow system becomes more unstable as the upward direction velocity of the plate or cylinder increases. The effects of the viscoelastic parameter, , and the micropolar parameter, , on the stability of the thin film flow become more pronounced as the upward direction velocity of the plate or cylinder increases. (2)Influence of cylinder radius on stability behavior of thin film flow: The film flow becomes more stable by increasing the radius of the cylinder as the cylinder moves either upward or downward. The effect of the cylinder radius on the stability of the thin film flow becomes less significant as the downward direction velocity of the cylinder increases. Conversely, the radius effect becomes more pronounced as the upward direction velocity of the cylinder increases. (3)Rupture analysis of thin liquid film on cylinder: The occurrence of film rupture is delayed as the value of the micropolar parameter, , is increased. Furthermore, the rupture time of the film flow decreases as the van der Waals potential effect increases. Conversely, increasing the surface tension or the cylinder radius delays the onset of the rupture process.

The paper investigates the stability of thin non-Newtonian liquid film flowing down on a vertical wall or cylinder using a long-wave perturbation method to solve for generalized nonlinear kinematic equations with free film interface. To begin with a normal mode approach is employed to obtain the linear stability solution for the film flow. The threshold conditions, the linear growth rate of the amplitudes and the linear wave speeds are obtained subsequently as the by-products of linear solutions. To further investigate practical flow stability conditions, the weak nonlinear dynamics of a film flow is presented by using the method of multiple scales. It is shown that the necessary condition for the existence of such a solution is governed by the Ginzburg-Landau equation. The subcritical stability, subcritical instability, supercritical stability and supercritical explosive state will be obtained from the nonlinear film flow system. Some practical examples will be shown in the present thesis in order to illustrate the effectiveness on stability of the viscoelastic coefficient, the flow index of pseudoplastic liquid, the yield stress of Bingham liquid, the micropolar parameter and the cylinder size on the conclusive results. (1)Stability analysis of a thin viscoelastic film flow When a viscoelastic liquid film flow is modeled as a non-Newtonian flow, it possesses the characteristics of the so-called cross-viscosity and elastic properties. As the gravity-driven fluid is in motion, the flow energy is partially consumed by internal viscous forces and dissipated as heat to the environment, and partially stored as strain energy and the elastic stresses cannot be relaxed at a certain frequency. The degree of stability of the viscoelastic film flow decreases as the value of k increases. (2)Stability analysis of a thin pseudoplastic film flow When a pseudoplastic liquid film flow is modeled as a non-Newtonian flow, it possesses the characteristic of shear thinning effect. Physically, the gravity-driven pseudoplastic fluid of thin film flow will decrease the effective viscosity, it can, therefore, increase the convective motion of flow. The decreasing flow index indeed plays a significant role in destabilizing the flow and is thus of great practical importance. (3)Stability analysis of a thin Bingham plastic film flow For the film flow in stable states, the larger yield stress of the Bingham fluid decreases the convective motion of flow and tends to stabilize the flow. However, the yield stress of the Bingham fluid increases the disturbance energy in unstable states. Therefore, the flow will become relatively unstable as the value of yield stress is increased. (4)Stability analysis of a thin micropolar film flow The effect of the microrotation and couple stress will be taken into account in the Non-Newtonian fluid with the suspension micro-particle. Because the vortex viscosity parameter of the microstructure in micropolar fluid will increase the effective viscosity, it can, therefore, reduce the convective motion of flow. The flow field becomes relatively stable for a larger . (5) Stability analysis of a thin film flowing down on a vertical cylinder When the film flows down the outer surface has a destabilizing effect as the cylinder with a smaller radius . This destabilizing effect occurs because the surface tension will produce large capillary pressure at a smaller radius of curvature. This will induce the capillary pressure and force the fluid trough to move upward to the crest. Thus, the amplitude of the wave is increased.

In the paper the three-dimensional source distribution method is applied to solve the nonlinear hydrodynamic forces on the trimaran ship advancing in waves. The nonlinear forces can be divided into two components, i.e. added resistance and lateral drifting force, which are caused by ship motions, radiation force, diffraction force and Froude-krylov force. The fluid considered here are assumed to be irrotational, incompressible and non-viscous and the solutions of the nonlinear hydrodynamic forces are treated in frequency domain. Using the panel method and source distribution method, the related hydrodynamic coefficients can be calculated by the boundary conditions and the ship motions can be solved. Based on the Salvesen’s method, the added resistance and lateral drifting force will be obtained from the ship motions and corresponding potentials. In the paper, the steady flow is also included to check the effect on the nonlinear forces with the different wave headings and different side-hull arrangements. From the comparisons of the theory and experiment, we find that the present technique can well predict the added resistance and lateral drifting force for the trimaran ship advancing in waves.
