We study turbulent mixing due to convection using a laboratory experimental model with two miscible fluids of different density with an initial top heavy density distribution. The fluids that form the initial unstable stratification are miscible and the turbulence will produce molecular mixing. The denser fluid comes into the lighter fluid layer and it generates several forced plumes which are gravitationally unstable. As the turbulent plumes develop, the denser fluid comes into contact with the lighter fluid layer and the mixing process grows. Their development is caused by the lateral interaction between these plumes at the complex fractal surface between the dense and light fluids date_type: published date: 2011 volume: 13 place_of_pub: Alemania pagerange: 13341-13341 event_title: 8th EGU General Assembly, EGU 2011 event_location: Viena, Austria event_dates: 03/04/2011 - 08/04/2011 event_type: other institution: Agronomos department: Matematica_Aplicada4 refereed: TRUE book_title: Geophysical Research Abstracts of 8th EGU General Assembly official_url: http://www.geophysical-research-abstracts.net citation: Tarquis Alfonso, Ana Maria and López-Gonzalez-Nieto, Pilar and Redondo, José Manuel (2011).
