WitrynaWhen a droplet impacts a solid surface, the entrapment of a submillimeter-sized bubble and the emission of a high speed jet can be observed at low impact velocities. In this work, we show that bubble entrapment occurs only on sufficiently hydrophobic surfaces within a narrow range of impact velocities.

WitrynaOne aspect of previous investigations that has received modest attention is the dynamics associated with the ver- tical jet that prevails during the droplet collapse portion of the impingement process. For a narrow range of We, very thin jets with attendant high velocity have been observed. Witryna13 lip 2024 · Existing studies have revealed that the dynamics of an impinging droplet is not only influenced by its physical properties but also affected by the surface wettability 7, 8, the substrate...

Witryna1 paź 2014 · Comparison between hydrodynamics of multijet atomisation with 2 and 3 impinging jets. • Drop size is closely related with azimuthal location of droplets formation. • Jet dynamics has similar influence in atomisation of 2- and 3-impinging jet sprays. • Atomizer geometry is particularly influential for 3-impinging jets sprays. • how are youtube playlist views countedWitrynaImpinging jets at low velocities form initially a sheet in a plane perpendicular to the plane containing the momentum vectors of the jets, as seen on Fig. 1. Waves are formed on the surface of this sheet and grow until sheet fragmentation into ligaments at a certain breakup length, which eventually break into droplets (Fakhri et al., 2010). how are you two doingWitrynaImpinging Jets and Droplet Dynamics. 18,988 views.
