采用经典分子动力学(MD)模拟方法研究了相分离(PS)对瑞利平台(RP)不稳定性的影响。Ni-Ag块体结构是在产生不同的PS长度尺度,λ(PS),相对于RP不稳定性长度尺度,λ(RP)的温度(2000 K和1400 K)。然后从块体结构切割出类菱形,并利用一定幅度和波长λ(RP)的扰动进行图案化。发现当λ(PS)
Classical molecular dynamics (MD) simulations are used to investigate the role of phase separation (PS) on the Rayleigh-Plateau (RP) instability. Ni-Ag bulk structures are created at temperatures (2000 K and 1400 K) that generate different PS length scales, lambda(PS), relative to the RP instability length scale, lambda(RP). Rectanguloids are then cut from the bulk structures and patterned with a perturbation of certain amplitude and wavelength, lambda(RP). It is found that when lambda(PS)
