Enhancing scalar transport in confined laminar flows by Francisco SASTRE MATESANZ Experimental research is carried out to shed light over the kind of some flow topologies and mechanisms that may enhance mixing in confined flows. The purpose is to understand said mechanisms to find suitable ways of optimization and application for the industry. A summary of results has been published in journals that appear in the Journal Citation Reports. Last but not least, I must mention that this path would have been highly untamed without the encouragement and spirit of my laboratory colleagues: Dr. David Vicente (strategy advisor), Dr. Ji Xu (code guru), César Enriquez (political advisor), Sergio Henriquez (human database), David Gutierrez (L A T E X consultant), Óscar Santiago (cultural provider), Rafel Clemente (expert in 3D printers), Eloy Millán (Galician sage), and others.
