Vortex ring refraction at large Froude numbers 1

Submitted for the MAR10 Meeting of The American Physical Society Vortex ring refraction at large Froude numbers1 KERRY KUEHN, MATTHEW MOELLER, MICHAEL SCHULZ, DANIEL SANFELIPPO, Wisconsin Lutheran College — We have experimentally studied the impact of a planar axisymmetric vortex ring, incident at an oblique angle, upon a sharp gravity-induced interface separating two fluids of differing densit...

Investigation of Cavity Flows at Low and High Reynolds Numbers Using Computational Fluid Dynamics By

Despite the amount of researchinto the cavity flow problem the prediction of the flow patterns, asso-ciated forces and acoustic phenomenaremains an unsolved problem. The coupling of the shear layerdynamics, the internal vortical structures and the acoustics of the cavity make it a very complex flowdespite the simple geometry. Once doors, stores and release mechanism are adde...

the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media

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...

Molecular Dynamics Simulations of Nanochannel Flows at Low Reynolds Numbers

In this paper we use molecular dynamics (MD) simulations to study nanochannel flows at low Reynolds numbers and present some new interesting results. We investigated a simple fluid flowing through channels of different shapes at the nano level. The Weeks-Chandler-Anderson potentials with different interaction strength factors are adopted for the interaction forces between fluid -fluid and fluid...
