Abstract in Spanish
Con un dispositivo experimental de relativamente bajo costo, consistente en un crióstato de vidrio y una cámara digital capaz de tomar imágenes a 240 cuadros por segundo hemos observado trayectorias de partículas sólidas de hidrógeno que siguen el flujo de helio líquido a temperaturas debajo de 2 K, alrededor de una esfera que oscila a 38 Hz. En algunas imágenes el movimiento es compatible con flujo laminar, mientras que a amplitudes grandes, donde podemos alcanzar números de Reynolds de unos miles para la componente normal, el flujo es claramente turbulento. En algunos de los videos obtenidos encontramos partículas que son aceleradas a velocidades bastante mayores que la velocidad de oscilación de la esfera.
Abstract in English
Using a relatively low cost apparatus, consisting of a glass dewar and a digital camera capable of taking images at 240 frames per second we have observed trajectories of frozen H_2 particles which follow the flow of liquid helium below 2 K, around a sphere oscillating at 38 Hz. In some of the images the motion is compatible with laminar flow, while at high amplitudes, where we can reach Reynolds numbers of a few thousand in the normal component, the flow is clearly turbulent. In some of the videos taken we find particles being suddenly accelerated to several times the velocity of the oscillating sphere.
