Electric Field Assisted Capillarity is a novel process which has the potential for the fabrication of hollow polymer microstructures as a single step process. The process has been shown to work experimentally on a microscale using PDMS. The process makes use of both the electrohydrodynamics of polymers at a microscale and also the capillary force on the(More)
For numerical simulation of electrodeposition in small features, we have developed a novel method that allows an explicit tracking of the interface between the electrolyte and the deposited metal. The method is implemented in the CFD package PHYSICA and validated by comparing the delivered simulation results with those achieved by real-life measurements(More)
Electric field Assisted Capillarity (EFAC) is a novel method for the fabrication of hollow microstructures in polymers. It involves both electrostatic and multiphase fluid dynamics modelling with special attention paid to surface tension due to the large capillary forces involved. This presents several challenges in the modelling, firstly due to the small(More)
Electric Field Assisted Capillarity (EFAC) is a novel process which has the potential for the single step fabrication of hollow polymer microstructures. The process has been shown to work experimentally on a microscale level using Polydimethylsiloxane (PDMS). The process makes use of both the electrohydrodynamics of polymer at a microscale and the voltage(More)
This paper provides an overview of some of the techniques and methodologies utilized in the modelling of complex systems that involve many interacting components with different physical properties over different spatial and temporal scales. Such systems are difficult to resolve, since they exhibit high levels of uncertainty. We discuss modelling strategies(More)
We demonstrate a "collection development decision support tool" that mines digital archive usage data. We want to better understand the University of Southern California (USC) Digital Archive's collection structure by analyzing the objects' characteristics, by analyzing the relationships between viewed objects, and by understanding usage trends over time.(More)
In this paper, the framework is described for the modelling of granu-lar material by employing Computational Fluid Dynamics (CFD). This is achieved through the use and implementation in the continuum theory of con-stitutive relations, which are derived in a granular dynamics framework and parametrise particle interactions that occur at the micro-scale(More)
