Nonlinear Dynamics of a Single Ferrofluid-Peak in an Oscillating Magnetic Field
If a magnetic field normal to the surface of a magnetic fluid is increased beyond a critical value a spontaneous deformation of the surface arises (normal field instability). The instability is subcritical and leads to peaks of a characteristic shape. We investigate the neighborhood of this instability experimentally under the influence of a temporal modulation of the magnetic field. We use a s...
متن کاملFerrofluid Dynamics of a Single-Peak under an Oscillating Magnetic Field
A magnetic field applied normal to the surface of a ferrofluid is temporally varied so as to exhibit nonlinear behavior. The overall effect will result in hydrodynamic and magnetic nonlinearities, in which the magnetic coupling between the fluid and the external field results in a hysteresis effect that serves as the primary nonlinearity of interest. A period doubling route is observed with var...
متن کاملExperiment and simulation of laminar and turbulent ferrofluid pipe flow in an oscillating magnetic field.
Laminar and turbulent pipe flow of a ferrofluid with an imposed linearly polarized, oscillating, magnetic field is examined here. Experimental results show a fractional pressure drop dependence on flow rate, magnetic field strength, and oscillation frequency. Calculations are presented, which show that ferrofluid theory can explain the flow phenomena in laminar and turbulent pipe flow. The mode...
متن کاملNonlinear deformation of a ferrofluid droplet in a uniform magnetic field.
This paper reports experimental and numerical results of the deformation of a ferrofluid droplet on a superhydrophobic surface under the effect of a uniform magnetic field. A water-based ferrofluid droplet surrounded by immiscible mineral oil was stretched by a magnetic field parallel to the substrate surface. The results show that an increasing flux density increases the droplet width and decr...

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...
