Abstract/Description
Aspects of terrestrial microgrids and ship power systems are examined. The work exposes a variety of technical synergies from these two power systems to effectively advance their technologies. Understanding their overlap allows congruent efforts to target both systems; understanding their differences hinders conflict and redundancy in early-stage design. The paper concludes by highlighting how an understanding of both systems can reduce the investment in research resources.

Abstract/Description
This paper elaborates a thermal analysis of a DC electromagnet cooled by high thermal conductivity discs, via which heat is conducted away from the hot spot to the heat sinks at inner and outer disc surfaces. In this work, a dimensionless mathematical expression for the hot spot temperature in the coil was derived and solved analytically. The solution was then verified numerically with a commercial FEA software. Subsequently, the model was employed to investigate the hot spot temperature...

In this work, a dimensionless mathematical expression for the hot spot temperature in the coil was derived and solved analytically. The solution was then verified numerically with a commercial FEA software. Subsequently, the model was employed to investigate the hot spot temperature variation with respect to the number of discs for a given magnetic performance. The study also examined how the change in heat flow direction, with respect to the number of discs, affected the overall thermal performance of an electromagnet. According to the results, electromagnets become thinner and longer as the number of discs increase, which in turn lowers the hot spot temperature. Furthermore, heat is observed to ow axially with smaller number of discs, whereas radial heat ow predominates as this number increases. In summary, the results infer that a thermally efficient electromagnet can be designed by minimizing the heat ow resistance in the coil, with shorter (or highly conductive) path for the hot spot to easily access the heat sink.
