WebIn this paper, we analyze the hydrodynamic behavior of the LBM pseudopotential models for the problem of the breakup of a liquid ligament triggered by the Plateau-Rayleigh instability. Simulations are performed at fixed interface thickness, while increasing the ligament radius, i.e., in the “sharp interface” limit. Web3.2 Savart–Plateau–Rayleigh instability of a water column. As observed by Félix Savart and Joseph Plateau, and confirmed theoretically by Lord Rayleigh, a column of liquid spontaneously breaks up into droplets under the influence of surface tension. An example of this process is given in the animation of Figure 13 for a column of water in air. how high movie meme https://montoutdoors.com
