Abstract: Plunging-flow dropshafts can entrain a large amount of air into sewer systems, pressurize downstream airspace, and cause potential sewer odor issues. In this study, a new design for a plunging-flow dropshaft is investigated ...

Abstract: AbstractDropshafts of deep tunnel systems can entrain a large amount of air, and the resulting air–water interactions cause potential safety issues. In this study, the air–water flow characteristics along a tunnel under ...

Abstract: The reliability of the flip chip package is strongly influenced by underfill, which has a much higher coefficient of thermal expansion (CTE) compared with other packaging materials and leads ...

Abstract: AbstractA hydraulic jump taking place in a partially filled pipe is responsible for rapid change in the pipeflow dynamics and air content. The pipeflow self-aeration at hydraulic jump in a closed pipe has not been studied ...
