Investigation of dense plumes in porous media using CsNO solute and phenolphthalein tracer.

We present results from the laboratory experiments performed to study the behaviour of dense plumes in porous media using Caesium Nitrate (CsNO) as the solute. Specifically, we consider the case of fixed volume release of a dense fluid into a saturated porous medium of lighter density. Our experiments consider the injection volume and concentration of CsNO and the porous medium permeability as experimental variables.
