“…Based on real-time drilling parameters, Ekpotu et al 36 used least-squares modeling and statistical analysis methods to analyze the depth of cut of reservoir rock. Wang et al 37 used particle flow mechanics theory simulation to analyze the transport characteristics of drilling fluid-carried rock chips in the wellbore. Ge et al 38 conducted water jet rock fragmentation experiments under true triaxial conditions and established rock damage energy criteria.…”

In this paper, first, the control principle of wall-mounted bistable jet components is analyzed, and the jet components and the main structures of the inner cavity are introduced. Then, the control equations, turbulence models, boundary conditions, and mesh partitioning of multiphase fluids are established sequentially, and the jet element mesh model was obtained. Finally, qualitative and quantitative analyses are conducted on the attachment process, switching process, and attachment point position. Results show that in the steady state of wall attachment, the fluid layer attached to the wall is the fluid flowing from the control channel on the wall side of the jet attachment, rather than the main jet. The geometric parameters of the jet assembly affect the stability of the jet assembly attachment to the wall and the location of the attachment point.
