Jet mixing of water in crude oil pipelines [PDF]
, 1990 The jet mixing of water in crude oil pipelines by single nozzle and multi-nozzle mixers was studied by dividing the mixing domain into to three regions. the penetration. near field and farfield regions.

High-pressure jet cutting with liquid CO2
, 2022 S.315-326With a developed experimental system a continuous liquid carbon dioxide jet with up to 3000 bar was realized. During the technological investigations the velocity and impulse force of high-pressure CO2 and water jets were analyzed.

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

Aerofoil behaviour at high angles of attack and at Reynolds numbers appropriate for small wind turbines [PDF]
, 2014 The aerodynamic characteristics of a NACA0018 aerofoil have been investigated experimentally for incidence angles ranging from 0° to 180° in closed-jet and open-jet wind tunnels with different blockage coefficients at Reynolds numbers from 60,000 to 140 ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Influence of high pressure water jet nozzles on cleaning action [PDF]
, 2006 In order to clarify the practical cleaning action on a working surface resulting from impinging water jets for wash jet nozzles, by means of a pressure sensitive film technique and an image processing method, we measured distributions of impact pressures
