Simulation of the mechanical deformation and movement of droplets under the influ-ence of strong electric fields (A05)

本课题主要研究强电场作用下的液滴动力学模型。感兴趣的主要问题是i)研究水滴振荡和绝缘表面上相关的放电行为，ii)建立电控液滴发生器的模型，以及iii)基于电喷雾特性的仿真。研究将采用一种新的电-水动力学模拟模型。该模型描述了包括对流流动和瞬态液滴充电效应在内的多流体问题的完整的准静电场动力学。

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.
