This study is aimed at the problems of traditional vortex tools in gas wells, including notable pressure losses and short effective distances. An organic combination of jet vortex drainage and gas production tools was designed and installed without additional power equipment. Based on the liquid film force balance model, gas–liquid two‐phase flow and turbulence models of the jet vortex tool were established...
An underwater open cavity, such as a submarine's open weapons firing tube, is a typical kind of structure that can induce fluid noise. To study the fluid noise generated by the submarine's open tube, greater attention is paid when the cavity's opening is vertical to the flow direction. This paper focuses on flow noise induced by an underwater cavity having openings under small attack angles, and simulations...
