论文摘要
液体离子在激光消融在液体环境中产生的灰尘等离子体中的作用尚不清楚。为此，我们利用了自相似方法来研究液体离子对等离子体膨胀前端的影响。除了超热电子分布外，流体方程还用于灰尘颗粒和离子物种。我们在不存在和存在液体离子的情况下处理扩展过程。已经解决了灰尘与离子初始数量密度比，超热因子Kappa，灰尘与电子初始温度比和尘埃离子原子数在膨胀前端的影响。我们的发现表明，在单个离子情况下，改变能量电子的超热性对灰尘离子扩展具有最大的影响。此外，我们观察到，液体离子的质量对双离子情况下的灰尘离子的动力学有最大的影响。
The role of liquid ions in the dusty plasma produced by laser ablation in a liquid environment is still unclear. For that purpose, we utilized the self-similar approach to investigate the effect of liquid ions on plasma expansion front. The fluid equations have been used for dust particles and ion species in addition to superthermal electron distribution. We treat the expansion process in the absence and existence of liquid ions. The impact of the dust-to-ion initial number density ratio, superthermality factor kappa, dust-to-electrons initial temperature ratio, and dust-ions atomic number on the expansion front has been addressed. Our findings show that in the single ion case, changing the superthermality of energetic electrons has the most significant influence on the dust ion expansion. Moreover, we observed that the mass of the liquid ions has the greatest effect on the dynamics of the dust ions in the double ion case.
