asir-55388	Li, Peishu; Gao, Ke; Wen, Yumin; Zhao, Yan	Analysis of Transient Flow Field and Rock Cuttings Trajectory in Large-Diameter Reaming Drilling	2024	17	.pdf	application/pdf	5373	211	51	Upon observing the velocity contour of the flow field in the return channel and debris discharge pipe after stabilization (Figure 3), it can be found that during large-diameter reaming drilling, the flow velocity at the bottom of the hole is relatively low, with a velocity of 0.21 m/s away from the debris discharge pipe, while the velocity near the entrance of the debris discharge pipe is higher, reaching 1.43 m/s at the entrance. The main reason is that two shorter debris discharge pipes converge in this area, causing a substantial increase in flow velocity due to the convergence of a large amount of fluid in this region.	cache/asir-55388.pdf	txt/asir-55388.txt
