WitrynaImpinging 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). Witryna1 sie 2024 · For example, a large contact area between the impinging droplet and target surface can enhance the heat transfer in spray cooling systems (Breitenbach et al., 2024) and minimizing the droplet–surface contact area is beneficial to delay, or even suppress ice nucleation in anti-icing applications (Mishchenko et al., 2010; Maitra et … iowa county snowmobile trails https://christinejordan.net
