Montaje experimental para el estudio de la mezcla generada por penachos turbulentos

Abstract

A simple laboratory model of turbulent mixing between two miscible fluids under an initial situation of top heavy stratification in a gravitational field has been performed. The mixing processes are generated by the evolution of a discrete set of unstable forced turbulent plumes. We describe the experimental setup, the laboratory instruments and the way the mixing processes are. We also describe the characteristic and construction of the instruments that are classified fluid flow instruments, electric instruments and video-digitalisation instruments. This laboratory model lets the corresponding turbulent mixing processes measuring the density profiles and the heights of the fluid layers by means of shadowgraph and direct flow visualization.
