Flow of foam past an elliptical obstacle.
To investigate the link between discrete small-scale and continuous large scale mechanical properties of a foam, we observe its two-dimensional flow in a channel, around an elliptical obstacle. We measure the drag, lift, and torque acting on the ellipse versus the angle between its major axis and the flow direction. The drag increases with the spanwise dimension, in marked contrast with a squar...
متن کاملDevelopment of a Direct Explicit Equation for Hydraulic Design of Semi-elliptical Channels
One of the common concrete channels in irrigation networks is the semielliptical prefabricated channels. Manning formula is usually used to design these channels. The cross-sectional area and the wetted perimeter are required to be calculated in Manning formula. There are no analytical solutions to directly compute these parameters. Thus, numerical integration methods are inevitably used. In th...
متن کاملEvolution of an elliptical bubble in an accelerating extensional flow
The manufacture of optical fibers typically involves taking a solid glass cylinder (a blank or preform), heating it up to melting temperature by feeding it through a cylindrical furnace (the drawing tower), and drawing the molten blank from the other end of the furnace at high speed (tens of meters per second). Since the drawing speed is much faster than the feeding speed (by a factor of at lea...
متن کاملElliptical instability of the flow in a rotating shell
A theoretical and experimental study of the spin-over mode induced by the elliptical instability of a flow contained in a slightly deformed rotating spherical shell is presented. This geometrical configuration mimics the liquid rotating cores of planets when deformed by tides coming from neighboring gravitational bodies. Theoretical estimations for the growth rates and for the non linear amplit...
