Three-dimensional viscous steady streaming in a rectangular channel past a cylinder

Autor: Willis, Nathan, Hohenegger, Christel

We consider viscous steady streaming induced by oscillatory flow past a cylinder between two plates, where the cylinder's axis is normal to the plates. While this phenomenon was first studied in the 1930s, it has received renewed interest recently fo

High Spots for the Ice-Fishing Problem with Surface Tension

Autor: Willis, Nathan, Tan, Chee Han, Hohenegger, Christel, Osting, Braxton

In the ice-fishing problem, a half-space of fluid lies below an infinite rigid plate (``the ice'') with a hole. In this paper, we investigate the ice-fishing problem including the effects of surface tension on the free surface. The dimensionless numb

An Isoperimetric Sloshing Problem in a Shallow Container with Surface Tension

Autor: Tan, Chee Han, Hohenegger, Christel, Osting, Braxton

In 1965, B. A. Troesch solved the isoperimetric sloshing problem of determining the container shape that maximizes the fundamental sloshing frequency among two classes of shallow containers: symmetric canals with a given free surface width and cross-

Small Scale Stochastic Dynamics For Particle Image Velocimetry Applications

Autor: Hohenegger, Christel

Fluid velocities and Brownian effects at nanoscales in the near-wall region of microchannels can be experimentally measured in an image plane parallel to the wall using, for example, evanescent wave illumination technique combined with particle image

A Variational Characterization of Fluid Sloshing with Surface Tension

Autor: Tan, Chee Han, Hohenegger, Christel, Osting, Braxton

Publikováno v: SIAM Journal of Applied Mathematics 77(3), p.995-1019 (2017)

We consider the sloshing problem for an incompressible, inviscid, irrotational fluid in an open container, including effects due to surface tension on the free surface. We restrict ourselves to a constant contact angle and seek time-harmonic solution
