Nonlinear dynamics of viscous droplets
Nonlinear viscous droplet oscillation are analysed by solving the Navier–Stokes equation for an incompressible fluid. The method is based on mode expansions with modified solutions of the corresponding linear problem. A system of ordinary differential equations, including all nonlinear and viscous terms, is obtained by an extended application of the variational principle of Gauß to the underlyi...
متن کاملNonlinear Oscillations of Viscous Droplets
This paper deals with the problem of non-linear droplet oscillations, whereas eeects of liquid viscosity are of our special interest. In the experimental part nite amplitude, axial-symmetric oscillations of small liquid droplets in a gaseous environment are studied. Experimental results are compared with available theoretical models. It was found that for a wide range of viscous damping the num...
متن کاملViscous Nonlinear Dynamics of Twist and Writhe
Exploiting the “natural” frame of space curves, we formulate an intrinsic dynamics of a twisted elastic filament in a viscous fluid. Coupled nonlinear equations describing the temporal evolution of the filament’s complex curvature and twist density capture the dynamic interplay of twist and writhe. These equations are used to illustrate a remarkable nonlinear phenomenon: geometric untwisting of...
متن کاملSingularities on charged viscous droplets
We study the evolution of charged droplets of a conducting viscous liquid. The flow is driven by electrostatic repulsion and capillarity. These droplets are known to be linearly unstable when the electric charge is above the Rayleigh critical value. Here we investigate the nonlinear evolution that develops after the linear regime. Using a boundary elements method, we find that a perturbed spher...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
