In this paper, we use a COMSOL Multiphysics® model to demonstrate the potential use of polymer microring resonator structures for optical biosensing applications. When the refractive index of the area surrounding the microring resonator changes, there is a shift in the resonance wavelength that can be monitored. We present simulated results of the spectral response with different refractive ...

The performance of a PEMFC depends on several factors, including the flow inside gas channels. Low gas velocity inside the channel can make water management more difficult, possibly causing water to accumulate and condense in certain regions of the cell. In the present work, COMSOL Multiphysics software was used to visualize and describe gas flow inside the channel of a PEMFC operating with ...
