IMPROVING ENERGY PARAMETERS OF OIL JET PUMPS
Bulletin of the National Technical University "KhPI". Series: Hydraulic machines and hydraulic units, 2022 The difficulty of extracting oil from great depths due to the huge amounts of sand, water and other impurities has led to the fact that well jet oil pumps are becoming more common. Their use in oil production is facilitated by such factors as practical insensitivity to the content of gas and other impurities dissolved in oil compared to other types of ...

The Bouncing Jet: A Newtonian Liquid Rebounding off a Free Surface [PDF]
, 2007 We find that a liquid jet can bounce off a bath of the same liquid if the bath is moving horizontally with respect to the jet. Previous observations of jets rebounding off a bath (e.g.
