In two dimensions, the singularities found include those described by the Stokes solution with a 120掳 angle, Craya's flow with a cusp on the free surface, Gurevich's flow with a free surface meeting a rigid plane at 120掳 angle, and Dagan and Tulin's flow with a horizontal free ...

We report an experimental study of the deformation of the free surface of a very viscous fluid when drained out of a container through a circular orifice. At some critical height of the fluid, the free surface deforms and forms a dimple. At later times, this dimple becomes a cusp. We ...

4 free surface flow: environmental fluid mechanics introduces a wide range of environmental fluid flows, such as water waves, land runoff, channel flow, and effluent discharge. the book provides systematic analysis tools and basic skills for study fluid mechanics in natural and constructed ...
自由液面液体压强中与大气联通(即与空气接触)的液面叫做自由液面(free surface),即船舶倾斜时船内舱柜中能自由变动的液体表面。自由液面分析可以模拟两个不混溶流体之间的自由移动界面,如气体-液体和液体-液体。[图片]Abstract The model covered in this analysis pe
The free surface flow and fluid in the upper water column converge on the swash front, since the fluid there is travelling faster than the mean flow velocity, leading to a rolling motion and an injection of high momentum fluid at the leading edge of the swash (Barnes and Baldock, 2010)....
The total fluid force acting on a differential element, dS, of the free surface has an arbitrary direction, and is given by (2.43)F=(Σ¯a⋅n−Σ¯w⋅n)dS where Σ¯w is the total stress tensor in the water, defined by Eq. (I-5.90). Similarly, Σ¯a is the total ...
FluidX3D implements the lattice Boltzmann method, a type of direct numerical simulation (DNS), the most accurate type of fluid simulation, but also the most computationally challenging. Optional extension models include volume force (Guo forcing), free surface (volume-of-fluid and PLIC), a ...
Deformable elastomeric spheres are evaluated experimentally as they skip multiple times over a lake surface. Some spheres are embedded with small inertial measurement units to measure the acceleration experienced during water surface impact. A model for multiple impact events shows good agreement between ...
