The hydraulic flocculates are employed in water treatment plants (WTPs), but may present problems during the mixing stage reducing the efficiency of treatment. In this context modeling of a hydraulic flocculate using COMSOL and a 1:10 scale model of the Maringá-PR Brazil city WTP flocculate was done. The WTP flocculate is shown in figure 1 and the model illustrating the acrylic flocculate ...

Thermal Analysis of Packaged Deep Ultraviolet LEDs

Deep Ultraviolet Light Emitting Diodes (DUV LEDs) are presently operating at a relatively low efficiency, thus large amount of LED driving power is dissipating in heat. Thermal heating degrades LED performance and decreases LED’s lifetime. The degradation of DUV LED devices with temperature increase makes thermal management a key issue for DUV LEDs. We present a thermal analysis of DUV LED ...

Constructing COMSOL Models of a Bacteriological Fuel Cell

R. Coker[1], J. Mansell[1]
[1]NASA - Marshall Space Flight Center, Huntsville, AL, USA

We have started constructing preliminary design COMSOL models of a bacteriologically driven \'fuel cell\' that is intended to process waste products, such as carbon dioxide and brine, from a crewed vehicle. At this early stage, this complex system is reduced to two electrodes separated by a membrane. The electrolyte is a brine appropriate for growing methanogenic bateria, though none are ...
