Soap Film Experiment to study Synchronized Waving of Grass
ثبت نشده
چکیده
Synchronized waving of grass blades in the presence of fluid flow has been observed in cases such as wheat field in wind, marine grass in tidal currents. The synchronous motion can have important environmental and ecological impact via mixing of fluid due to waving. We use a twodimensional analog of these phenomenon in a gravity driven soap film tunnel. Nylon filaments attached to the boundaries of the soap film play the role of grass. Movie shows characteristics of fluid flow in and out of grass blades using soap film experiment with micron sized particle embedded in film.

In-situ observation of catenoid formed by soap film: as simple experiment for physics student
The solution to the Euler-Lagrange equation is extremal functional. In order to understand that the functional is stationary at local extrema (maxima or minima), we propose the physics experiment of catenoid formed by soap film. Catenoid is formed between two coaxial circular rings. Mathematically the catenoid is a kind of the minimal surfaces. Using soap film, the catenoid is made between two ...
متن کاملIn-situ observation of catenoid formed by soap film: Dynamical behavior of catenoid
Catenoid is the equilibrium shape formed between two coaxial circular rings. Mathematically the catenoid is a kind of the minimal surfaces. The catenoid is made by using soap film and we performed in-situ observation of catenoid by varying distance between two rings. It is shown that the shape of soap film does interesting behavior. The behavior can be explained from the point of view of the dy...
متن کاملInstability of the Kolmogorov flow in a soap film.
We examine the instability of a soap film flow driven by a time-independent force that is spatially periodic in the direction perpendicular to the forcing (Kolmogorov flow). Linear stability analysis of an idealized model of this flow predicts a critical Reynolds number R(c) is approximately equal to the square root of 2. In our soap film experiment, we find a critical value R(c) is approximate...
متن کاملSoap-film dynamics and topological transitions under continuous deformation∗
The response of a soap film to the continuous deformation of its wire boundary is considered, with particular attention to the topological transitions that can occur at critical stages of the deformation process. Two well-known examples that have been studied by both theory and experiment are the catenoid suspended between circular wires in parallel planes, and the Möbius-strip soap film spanni...
متن کاملInteraction of two flapping filaments in a flowing soap film
Using the immersed boundary method, we have simulated the motion of two flexible filaments in a flowing soap film, which was experimentally studied by Zhang et al. @Nature ~London! 408, 835 ~2000!#. We found numerically two distinct modes of sustained oscillation of the two filaments: parallel flapping and mirror-image clapping, depending on the separation distance between the two filaments.
