商用マルチフィジックスソフトによる再生可能エネルギーへの適用

抄録

It is necessary to use multiphysics analysis approach to investigate numerically the way how to get renewable energy and its transformation to electric power through energy harvesting techniques. In this article, we review COMSOL Multiphysics, commercial finite-element analysis software, and its application examples in renewable energy and energy harvesting. As a result, it is found that COMSOL Multiphysics is very applicable in solving various scientific problems, where there are many strong couplings such as fluid-structure interaction, structure-acoustic interaction, electromechanical coupling. For thermoelectric conversion, it is observed that COMSOL Multiphysics provides for PDE interface in order to implement the user's defined equations. Piezoelectric harvesting example is introduced to verify the ease in use of GUI of COMSOL Multiphysics.
