Résumé
This study explores the fluid dynamics of a Newtonian jet injected horizontally into a viscoplastic (yield stress) ambient fluid, a process relevant to various industrial applications, including jet cleaning process in oil and gas wells. To replicate industrial scenario, a perforated wall is considered between the nozzle and the tank wall, dividing the flow domain into two zones. We focus on the effects of key parameters, including the perforation diameter and the rheological properties of the ambient fluid, on jet behavior. The jet radius is used as a main metric to quantify mixing, while self-similarity is examined across varying conditions to provide insights into jet dynamics. The results reveal that a reduction in the perforation diameter leads to an increase in jet radius in the first zone, while causing a decrease in the second zone. In addition, the jet maintains its self-similar behavior, regardless of the perforation size. Furthermore, the presence of a viscoplastic fluid contributes to a decrease in the jet radius in both zones and deviate from self-similarity behavior, highlighting the significant impact of yield stress on the jet flow dynamics. These findings provide valuable insights into jet flow and can be leveraged to optimize jet cleaning processes, with the dimensionless results allowing for their extension to a range of relevant applications involving jets and non-Newtonian fluids, including liquid-in-liquid printing, cleaning-in-place systems, and industrial mixing operations.
