The objective of this thesis is to study the convective motions in binary mixtures and two-phase fluids. A critical analysis will be conducted on the methodologies used to visualize the onset and dynamics of convection, evaluating their advantages and application limitations. In parallel, the thesis will provide a detailed review of the state of the art of Rayleigh-Bénard convection in liquid-liquid two-phase systems and binary mixtures. The aim is to highlight the key findings in the scientific literature concerning the role played by the confinement of the convective cell and the intensity of the thermal gradient, identifying the most relevant developments and the ongoing challenges in understanding and modeling these complex motions.
Obiettivo del lavoro di tesi è lo studio dei moti convettivi di miscele binarie e fluidi bifasici. Verrà condotta un'analisi critica delle metodologie impiegate per la visualizzazione dell'innesco e delle dinamiche convettive, valutandone vantaggi e limiti di applicazioni. Parallelamente, la tesi prevede una rassegna dettagliata dello stato dell'arte della convezione di Rayleigh-Bénard in sistemi bifase liquido-liquido e miscele binarie. L’obiettivo è mettere in luce i risultati chiave della letteratura scientifica in relazione al ruolo svolto dal confinamento della cella convettiva e dall'intensità gradiente termico, individuando gli sviluppi più rilevanti e le sfide ancora aperte nella comprensione e modellizzazione di questi moti complessi.

Abstract
The objective of this thesis is to study the convective motions in binary mixtures and two-phase fluids. A critical analysis will be conducted on the methodologies used to visualize the onset and dynamics of convection, evaluating their advantages and application limitations. In parallel, the thesis will provide a detailed review of the state of the art of Rayleigh-Bénard convection in liquid-liquid two-phase systems and binary mixtures. The aim is to highlight the key findings in the scientific literature concerning the role played by the confinement of the convective cell and the intensity of the thermal gradient, identifying the most relevant developments and the ongoing challenges in understanding and modeling these complex motions.File | Dimensione | Formato | |
