The project is concerned with the modeling of droplet dynamics under the influence of strong electric fields. The main problems of interest are i) investigation of water droplet oscillations and the related electrical discharge behavior on insulating surfaces, ii) modelling of electrically controlled drop-on-demand generators and iii) simulation based characterization of electrosprays. A novel electrohydro-dynamical simulation model will be employed in the investigations. This model describes the full electroquasistatic field dynamics for multi-fluid problems including convective current flow as well as transient droplet charging effects.

该项目涉及强电场影响下的液滴动力学建模。感兴趣的主要问题是i）水滴振荡和绝缘表面上相关放电行为的研究，ii）电控按需滴发生器的建模以及iii）基于模拟的电喷雾表征。研究中将采用一种新颖的电流体动力学模拟模型。该模型描述了多流体问题的完整电准静态场动力学，包括对流电流以及瞬态液滴充电效应。
