Resumen
El presente trabajo consiste en un estudio de forma experimental de la influencia de la viscosidad de un líquido cuando se hace impactar sobre éste con un disco a velocidad constante. Cuando esto ocurre, se forma una cavidad de aire que posteriormente se cierra y genera un chorro líquido conocido como chorro de Worthington. A pesar de que en principio se podría pensar que la viscosidad amortigua este tipo de fenómenos, se ha visto que cuando el fluido es viscoso, se forma un chorro muy definido que avanza a gran velocidad. El objetivo principal es obtener los de los experimentos (cavidad y chorro) mediante análisis de imágenes, elaborando para ello códigos especiales. El objetivo final es estudiar la influencia del tamaño del disco, la velocidad y la viscosidad del líquido en los resultados del problema.
The present work consists of an experimental study of the influence of the viscosity of a liquid when it is impacted with a disk at constant velocity. When this occurs, an air cavity is formed which subsequently closes and generates a liquid jet known as Worthington jet. Although in principle it could be thought that viscosity dampens this type of phenomena, it has been seen that when the fluid is viscous, a very defined jet is formed that advances at high speed. The main objective is to obtain those of the experiments (cavity and jet) by means of image analysis, elaborating special codes for this purpose. The final objective is to study the influence of disk size, velocity and fluid viscosity on the results of the problem.
