Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs exclusively use Solid Oxide Fuel Cells with some developments in high temperature polymer electrolyte membranes ...

In this panel session we present numerical models for computing the current density, field distribution and AC losses in high-temperature superconducting tapes. The tapes have a rectangle cross section for two-dimensional geometries. The numerical models are tested by comparing the calculation results with the predictions of analytic solutions for simple geometries. We used it successively for ...

A computer controlled microwave exposure system and specialized applicators were constructed for the purpose of facilitating accurate observations of microwave radiation effects on uninfected and infected biological tissue in vitro and in vivo under different electromagnetic modalities and exposure configuration. To address diverse requirements, three different applicators were developed: a ...

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 ...

Multiphysics simulations play an important role in researchanddevelopment in almost all disciplines. Therefore it is necessary to teach them at the universities to provide the industry with well-trained graduate students. In our lectures about the finite element method we use a simple but rich enough example problem, which can be solved analytically. By comparing numerical and analytical ...

As it is known nano-sized emitters (such as atoms, quantum dots and point defects in diamonds) interaction with nano-environment leads to drastic changes of their decay rate and therefore lifetime (Purcell effect). To calculate the influence in general one needs to solve equations of quantum electrodynamics. However in weak interaction limit these emitters can be considered as point electric ...

I introduce a model of fluidized reactor which, in presence of heterogeneous platinum-based catalyst, decomposes liquid formic acid producing gaseous mixture of carbon dioxide and hydrogen as the product. I treat the physical system as a (Class II) mixture of four constituents - namely formic acid (FA), Platinum micro-pellets (Pt), carbon dioxide (CO_2) and hydrogen (H_2) - which can be, without ...

In this work, a bimetallic strip based thermal sensor was designed using MEMS module of COMSOL Multiphysics® software to monitor the temperature rise in insulating oil which was used as coolant in transformers. The bimetallic strip was designed with different shapes such as cylindrical, rectangle, square & conical and different compositions such as Al/Steel Alloy and Fe/Cu which can withstand ...

A class of semiconducting detectors, operated at temperature T~50mK, has direct application to the search for dark matter particle, when are able to simultaneously measure both the ionization and phonons created by particle interactions. We explore the effect of space charge accumulation in a germanium p-type point contact detector which arises due to the auto-ionization of hydrogenic ...
