This article will study the impact of a liquid jet with a flat surface, from a dynamic point of view. The surface where the liquid jet impact will take place has been positioned both perpendiculars to the direction of the jet and at a certain angle. To determine how the impact of the liquid jet takes place in the immediate vicinity of the plane plate, a CFD simulation is performed. The obtained results allow us to study two situations, one that concerns the occurrence of the hydraulic jump during the impact and the second will allow us to analyze the evolution of the jet symmetry. It is known that the impact of a liquid jet with a surface is quite complex. To solve this, the VOF (volume of fluid) model was used. The obtained results allow us to visualize the evolution of the liquid jet in the form of a complex geometric shape that at the extremities is followed by a hydraulic jump and the fragmentation of a part. The behavior of the impact of the jet with a surface inclined at 45°, shows that there is an asymmetry of the contact fingerprint as the jet inclines towards the normal straight-line surface. The main objective of the present simulations is to experimentally investigate the effect of the angle of inclination of the jet and of the fluid flow on the initial imprint formed at the contact and on the post-fragmentation mode of the complex geometrical structure formed.
