3D modeling of evaporation of water injected into a plasma jet

3D effects of the radial injection of water jet into the swirl and non-swirl plasma jets are clarified numerically. The plasma-droplet two-way interactions are modeled by coupling Lagrangian approach for droplet behavior with an Eulerian approach for plasma flow under the dense loading. The effect of radial injection of the water jet on the temperature and flow fields of the swirl and non-swirl plasma jets is studied numerically. Mass concentration of the evaporated vapor is also predicted. The local deformation of the thermo-fluid fields of the plasma jet is stronger for higher droplet loading. Evaporation rate is decreased with increasing the droplet loading as well as swirl velocity. Mixing of vapor with plasma is stronger in the presence of swirl.
