Master's thesis of Engineering: Study of isolated mixing regions using Newtonian fluids in mechanically stirred vessels

The main aims of this study are to: understand the phenomena of isolated mixing regions (IMRs) in Newtonian fluids agitated in mechanically stirred vessels, in particular, the formation of core torus, using experimental studies; investigate the behavior of IMRs structures by manipulating the operating variables such as impeller rotational speed and direction, as well as geometrical variables such as impeller types and baffle location; investigate the temporal chaotic mixing using different speed modulation protocols.
