The micro-nanometer sized droplets have tremendous applications in bio-diagnostics, polymerization processes etc. In this work, we numerically investigate the droplet formation process of silicone oil in aqueous solution in a MFF device. A conservative level-set method is adopted to ... Mehr lesen
Experiments have been conducted with water at velocities from ~0.015-0.77 m/s to determine the permeability of 50 mm thick commercially available 30, 40, 50 and 80 Pores Per Inch (PPI) Ceramic Foam Filters (CFF) used for liquid metal filtration. Measurements were made using two different ... Mehr lesen
Microfluidic devices and lab-on-a-chip (LOC) require the ability to transport or pump reagents or reaction products, the ability to effectively mix small volumes of fluid, and provide direct data display. Surface acoustic wave (SAW) driven acoustic streaming generated by a piezoelectric ... Mehr lesen
It is frequently necessary to electrically heat gases; a convenient geometry is the familiar tube-in-shell heat exchanger, where the tube side is modified for electrical heater-rods, and the baffled shell side contains the flowing gas, as indicated in Fig. 1. However, this modification ... Mehr lesen
The Direct Methanol Fuel Cell (DMFC) working is dependent on the concentration of methanol in water before it is introduced in the anode. DMFC has a high energy density when generating electrical power from fuel, and is an attractive power source for portable devices. A fundamental ... Mehr lesen
In the Andean region of Southern Peru, poverty and climate are extreme: at 4000mt asl, insolation is among the highest in the world but the temperature varies more than 30 degrees between day and night. At the community of Livitaca (Cuzco), the association “Ingegneria Senza Frontiere” is ... Mehr lesen
Geothermal heat production from deep reservoirs (5000-7000 m) is currently examined, not only in Germany. Our reference set-up consists of two pipes within a single borehole: one for pumping. We examine a design, where a single borehole splits into two legs at a certain depth. The two ... Mehr lesen
Polishing is one of the oldest finishing processes. However, exposure to emissions of crystalline silica dust is high. Some toxicological studies have identified this pollutant as responsible for a particular type of lung cancer, silicosis. Operational solutions are needed for reducing ... Mehr lesen
Single stage centrifugal pumps are widely used in several engineering fields such as: room conditioning, energetic cycles, automotive industry, home care, etc. Thus, the possibility of simulate their behaviour, in terms of pressure increase and mass flow rate, is helpful in reducing ... Mehr lesen
Simulations with COMSOL Multiphysics were performed, in order to analyze the gas flow patterns during the induced ignition of gases. Simplified calculations were performed. The ignition spark was assumed to have a temperature of 2000 K and a laminar flow was selected. 2D calculations ... Mehr lesen
