The behavior of a negatively buoyant jet in laminar conditions that result from the injection of lighter fluids downwards into a large container of homogeneous fluid of denser density was studied numerically using OpenFoam with the finite volume method. The fluid characteristics effect on the evolution of the pure water injected in the tank full of salt water has been investigated particularly the molecular diffusivity that affects the mixing layer, the relative difference of density between two liquids, and the kinematic viscosity of the salt water that has an important effect in the transient phase as well as the subsequent steady state in terms of stationary penetration depth and jet profile.
