15 صفحه اولDepth-averaged model for hydraulic jumps on an inclined plate.
We examine the dynamics of a layer of viscous liquid on an inclined plate. If the layer's upstream depth h(-) exceeds the downstream depth h(+), a smooth hydraulic jump (bore) forms and starts propagating down the slope. If the ratio η = h(+)/h(-) is sufficiently small and/or the plate's inclination angle is sufficiently large, the bore overturns and no smooth steadily propagating solution exis...
متن کاملEffect of contact line dynamics on the thermocapillary motion of a droplet on an inclined plate.
We study the two-dimensional dynamics of a droplet on an inclined, nonisothermal solid substrate. We use lubrication theory to obtain a single evolution equation for the interface, which accounts for gravity, capillarity, and thermo-capillarity, brought about by the dependence of the surface tension on temperature. The contact line motion is modeled using a relation that couples the contact lin...
متن کاملFriction Experienced by a Particle Moving on Arough Inclined
We present results from molecular dynamics simulations of a sphere moving down an inclined plane made rough by glueing other spheres to it. The moving sphere experiences an eeective friction force due to collisions with the balls on the plane, and can maintain a steady state with a constant mean velocity for a certain range of inclination angles of the plane. Although the friction force is due ...
متن کاملOptimized Control of Vortex Shedding from an Inclined Flat Plate
Optimal control theory is combined with the numerical simulation of an incompressible viscous flow to control vortex shedding in order to maximize lift. A two-dimensional flat plate model is considered at a high angle of attack and a Reynolds number of 300. Actuation is provided by unsteady mass injection near the trailing edge and is modeled by a compact body force. The adjoint of the lineariz...
