An important part of the society considers an increased share of renewable energies as an integral part of a strategy towards a sustainable future. As far as heat supply is concerned, this can be achieved using solar thermal collectors, borehole heat exchangers or trough the combustion of biomass. This article shows two applications of two configurations of twisted conduit inside the external ...

We have developed Thor: a pulsed power accelerator for performing dynamic material experiments. The design was aided by using the COMSOL Multiphysics® software with the AC/DC Module and RF Module. Our design process involved optimizing the impedance of the system while maintaining a good margin against electrical breakdown. By using a three-dimensional electromagnetic model of the entire power ...

Microwave sensing and monitoring is very attractive for biological applications because of their sensitivity to water and dielectric contrast. Direct detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is considered as a problem of a great importance. Nowadays, however, microwave technique for localized testing biological ...

Using a Realistic Human Head model to simulate the effect of electrical stimulation can be useful in understanding field distribution in the brain and therefore, the actual point of stimulation before doing it on human subject. With the help of this model, parameters like the stimulus strength as well as electrode placement and its effect can be tested much more easily while targeting a ...

The microband design of microelectrodes is a cost-effective and easily-fabricated compromise combining convergent mass transport, due to microscale width as a critical dimension, and high output currents due to the macroscopic length. Among the various techniques available for microband electrode fabrication, screen-printing stands out as an inexpensive approach. The application of cross cutting ...

This analysis evaluates the importance of the lateral component of flow on the infiltration of water from parallel strip sources of water on the soil surface. Flow from such sources will be two-dimensional, having both vertical and lateral components. Here we examine the effect of the spacing between parallel strip sources and the texture of the soil on the rate of infiltration through a given ...

This poster describes a simulation of reverse saturable absorption in a solution C_60 molecules using the COMSOL Multiphysics® software. The optical processes in C_60 can be modeled through a five-level system. The energy states include three levels of the singlet state, coupled to two levels of an excited triplet state. The optical process is modeled with simple rate equations coupled to a ...

Scraped surface heat exchangers (SSHEs) are commonly used in the food, chemical, and pharmaceutical industries for heat transfer, crystallization, and other continuous processes. One of the factor posing difficulties to heat transfer is viscosity. Highly viscous fluids tend to generate deep laminar flow, a condition with very poor heat transfer rates and high pressure losses involving a ...
