Abstract Hydraulic jetting is a form of fracturing that involves using a high-pressure jet of water to create fractures in the
reservoir rock with a nozzle serving as the central component of the hydraulic sandblasting perforation tool. In
this study, the flow behavior of the nozzle is simulated numerically in the framework of a SST k-ω turbulence
model. The results show that the nozzle structure can significantly influence the jet performance and related cavitation effect. Through orthogonal experiments, the nozzle geometric parameters are optimized, and the following
configuration is found accordingly: contraction angle 20°, contraction segment length 6 mm, cylindrical segment… More >
