RISStudy on the Influence of Characteristic Scale Ratio of Irregular Wall on the Impact Characteristics of Drilling Water Jet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The impact of drilling water jets is closely related to the structure of the impact surface. The actual inner wall of the borehole has geological structures such as randomly distributed concave, convex, and ...
Study on the Dynamic Characteristics and Aging Mechanism of Water Jet Impact in Boreholes Under Temperature Coupling Effect
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The impact efficiency of water jets is closely associated with their transient characteristics and thermal effects. However, existing studies have predominantly focused on macroscopic impact effects, largely ...
