Experimental Stuy of Water Jet Break-Up in an Supercritical Carbon Dioxie

Water jets in systems at low pressure have been frequently stuie an some moels for the preiction of spray cone angle (θ/2), intact-surface break-up length (L1), an intact-core break-up length (L2) have been evelope. Complete stuies of jets in supercritical receiving meium have not been carrie out; for this reason, in this work, an experimental stuy on the observation of water jet break-up in supercritical carbon ioxie has been propose. Different operating conitions were teste an jet characteristics in terms of θ/2, L1, an L2 were stuie. The obtaine ata were first fitte using the moels propose in the literature; then, a moel was evelope in this work, which takes into account the influence of pressure in the evaluation of the spray cone angle. The proposal of a pressure-epenent correlation reveale to be effective in the escription of the sprays generate in supercritical conitions.
