Experimental and numerical investigation of interacting cavitation bubbles in nanoparticle production using a novel laser pulse matrix method

在一个联合的实验/数值方法，相变，传热传质和波动动力学和激光烧蚀过程中形成的纳米粒子在水溶液中的性能之间的关系将被详细检查。假设所产生的空化泡中的随时间变化的状态属性对颗粒分布有影响，并且通过控制空化泡的形成来间接影响所产生的颗粒属性是可能的。实验和数值数据的分析的基础上，间接影响颗粒特性的经验策略是来自有针对性的，空间和时间延迟的空化气泡在目标的产生，并通过数值模拟研究其作用机制。

In a joint experimental/numerical approach, the relationship between phase transition, heat and mass transfer and wave dynamics and the properties of the nanoparticles formed during laser ablation in aqueous solution will be examined in detail. The hypothesis is that the temporally variable state properties in the generated cavitation bubble have an effect on the particle distribution and that an indirect influence of the generated particle properties by controlling the cavitation bubble formation is possible. Based on the analysis of the experimental and numerical data, empirical strategies for indirectly influencing the particle properties are to be derived by targeted, spatially and temporally delayed generation of cavitation bubbles at the target and investigated for their mechanisms of action by numerical simulation.
