Computational fluid dynamics implementation and optimization of electrohydrodynamics’ two-phase leaky dielectric model
The leaky dielectric model from electrohydrodynamics (EHD) was incorporated into the computational fluid dynamics (CFD) software called OpenFOAM®. Based on the used literature, it can be said that this implementation of the mentioned model is the most complete. Three sets of two-phase simulations were done. The first set was one- dimensional. I...

Implementation of the electrohydrodynamics’ perfect dielectric model in OpenFOAM
The electrohydrodynamics’ (EHD) perfect dielectric model was added into computational fluid dynamics (CFD) software OpenFOAM in order to improve its usability for the EHD field and specifically for the mentioned model. Based on the investigated literature, it can be said that this is the most complete implementatiton of the said model. Two se...

Review of electrospray observations and theory
While a liquid is dripping out of a capillary tube, there is a possibility to affect the characteristics of the exiting flow in certain ways. One of the ways already used is by introducing an electric field that can be used to change the average droplet diameter and the droplet size distribution. This process is called electrospraying, while the th...
