Resumen
En esta Tesis doctoral se presentan estudios experimentales dirigidos a analizar la generación controlada de burbujas en diferentes configuraciones y al estudio de la dinámica colectiva de enjambres de burbujas que evolucionan debido a la coalescencia. En la primera parte, se analizan de forma experimental dos métodos diferentes destinados al control activo del proceso de generación de burbujas en corrientes no confinadas de agua-aire en configuración de co-flujo. La segunda parte de esta Tesis está dirigida al estudio experimental de la dinámica de la población de burbujas en enjambres confinados que ascienden debido a la flotabilidad a altos números de Reynolds cuya evolución está fuertemente condicionada por la coalescencia de las burbujas.
This PhD dissertation presents experimental studies based on the controlled bubble generation in different configurations as well as on the dynamics of confined bubble swarms whose evolution is driven by coalescence. In the first part, two different methods to actively control the bubble formation process in unbounded air-liquid co-flowing streams are experimentally analyzed. The second part of the dissertation is focused on the experimental analysis of the dynamics of a population of bubbles within a confined swarm of bubbles rising at high-Reynolds number driven by buoyancy, whose evolution is strongly dominated by the bubble coalescence.
