Industrial demands for more compact heat exchangers are a motivation to find new technology features. Electrohydrodynamics (EHD) is introduced as a promising phenomenon for heat transfer enhancement mechanisms. Similar to any new technology, EHD has not been understood completely yet and requires more fundamental studies. In boiling phase change phenomena, nucleation is the dominant mechanism i...

We applied a participatory design approach to define the objectives, characteristics, and features of a "data profiling" tool for primary care Electronic Health Data (EHD). Through three participatory design workshops, we collected input from potential tool users who had experience working with EHD. We present 15 recommended features and characteristics for the data profiling tool. From these r...

The purpose of this research was to produce multi-dimensional scaffolds containing biocompatible particles and fibres. To achieve this, two techniques were combined and used: T-Junction microfluidics and electrohydrodynamic (EHD) processing. The former was used to form layers of monodispersed bovine serum albumin (BSA) bubbles, which upon drying formed porous scaffolds. By altering the T-Juncti...

EHD printing of discrete conducting polymer arrays, bridging the electrodes for highly sensitive chemiresistive gas sensors.

In this work, a numerical model for the simulation of two-phase electrohydrodynamic (EHD) problems is proposed. It characterized by physically consistent treatment surface tension as well jump in electric material properties. The formulation based on finite element method enriched with special shape functions, capable accurate capturing discontinuities both fluid pressure and gradient potential...

Abstract Wearable electronic devices are evolving from current rigid configurations to flexible and ultimately stretchable structures. These emerging systems require soft circuits for connecting the various working units of overall system. This paper presents fabrication by electrohydrodynamic (EHD) inkjet-printing technique. Multi-nozzle EHD printing head is employed rapid electric on a wide s...

Electrohydrodynamic (EHD) drying is an energy-efficient method. This novel technology operates at room temperature, which makes it particularly suitable for biomaterials that contain heat-sensitive compounds. It has a higher rate than other low-temperature methods, such as solar and freeze-drying. However, its not high enough to compete with conventional thermal hot-air drying. For industrial a...
