Witryna16 lut 2024 · Published 16 February 2024. Physics, Engineering. We investigate experimentally the jet formed by the collapse of a cavity created by the impact of a drop on a pool of the same aqueous liquid. We show that jets can emerge with very different shapes and velocities, depending on the impact parameters, thus generating droplets … Witryna10 lis 2024 · The chemical composition of the droplet changes as the level of salts increases and the droplet crystallizes in a solid state. ... , where it was shown that for an impinging jet, all LES models are capable of capturing small-scale dynamics, and WALE and ...

Witryna5 lis 2024 · In this chapter, spray cooling is reviewed from two aspects: the entire spray (spray level) and droplets (droplet level). The discussion on the spray level is focused on the spray cooling performance as a function of fluid properties, flow conditions, surface conditions, and nozzle positioning. Witryna12 kwi 2024 · In this paper, we focus on the evolution of jets that form during the recoil of impinging drops on partially wetting hydrophilic substrates composed of cylindrical …
WitrynaThe current work experimentally investigates the flowfield characteristics of an under-expanded turbulent jet impinging on a solid surface for various nozzle-to-plate distances 2.46 D j , 1.64 D j , and 0.82 D j ( D j is the jet hydraulic diameter), and nozzle pressure ratios (NPRs) ranging from 2 to 2.77 . Planar particle image velocimetry (PIV) …
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. earth creations perthWitrynaImpinging Jets and Droplet Dynamics. 18,988 views.
