Estudio por simulación de transiciones de fase iniciadas por nucleación

Abstract

Este trabajo titulado “Estudio por simulación de transiciones de fase iniciadas por nucleación” tiene como eje central el estudio del proceso de nucleación. La nucleación es el fenómeno físico por el cual una fase metaestable (por ejemplo, un líquido calentado por encima de su temperatura de ebullición) sufre un cambio de fase de primer orden y se convierte en la fase estable a las condiciones a las que se encuentra. Este proceso que estamos acostumbrados a ver en nuestra vida cotidiana (congelación de agua en el frigorífico, ebullición en la olla etc.) suele darse de manera heterogénea, es decir, la fase creciente lo hace ayudada de las impurezas o las paredes presentes en el sistema. Sin embargo, la ciencia se encuentra aún lejos de entender este proceso heterogéneo y los esfuerzos se centran en la nucleación homogénea, es decir, aquella que se da sin ayuda ni de impurezas ni de paredes y que resulta más sencilla de estudiar. El estudio de los fenómenos de nucleación de manera experimental es especialmente complejo, debido a que este proceso tiene una naturaleza estocástica, aleatoria. Esto quiere decir que no se conoce ni el momento exacto ni el lugar exacto en el que se dará...
