In Vietnam, the solution of designing and constructing deep foundation pits with geology sandy or clayey sand is very difficult, especially in case soil mix mud. some pits, unreasonable treatment causes bottom plug pit to be pushed up not pump a dried. Solving those problems, this article introduces particular study, sealing for no14 Yen Xa drainage works Jet grouted hydraulic barriers. To trea...

one of the most common methods for controlling and increasing maneuverability of projectiles, especially the ones which move at high altitude and in low density air, is using lateral or reaction jets. the resultant force of the reaction jet is related to the jet and flow parameters. for finding their relation experimental, numerical, and analytical methods have been used. in order to change the...

in this paper, construction of triplet atmospheric plasma jet using argon, air, oxygen and nitrogen gases is reported. bactericidal effect of the plasma jet is also investigated. to that end, longitudinal geometric configuration for the electrodes was chosen because it would increase the jet length. electrical characteristics, jet length dependencies on the applied voltage and gas flow rate wer...

A round liquid jet in a gaseous crossflow (water in air) was observed over a range of conditions in order to investigate the relationship between the final width of the droplet cloud and the momentum ratio between the jet and the crossflow. The motivation for this work is as it relates to aerial fire suppression – that is, the use of aircraft to drop water or other fire retardant products onto ...
