Скачать или смотреть Jet against viscoelastic droplet

The video
is recorded with a high-speed camera at 50k frames per second, showing a liquid jet impacting a water droplet with PEO 600k 1 wt% The jet travels at 33.5 m s−1 impacting a droplet with a diameter of 2.21 mm. The jet travels a distance larger than drop diameter, but due to the viscoelastic effects of the droplet, it gets sucked back into the droplet. It is part of the publication Impact of a microfluidic jet onto a pendant droplet (https://pubs.rsc.org/en/content/artic... and belongs to the project entitled Penetrating jets in soft substrates: towards controlled needle-free injections.
