triboelectric nanogenerators

Please login with a confirmed email address before reporting spam

Hello everyone, I'm currently researching triboelectric nanogenerators. Their principle involves a PTFE film fixed at one end oscillating vertically under wind energy at a certain wind speed. This periodic flapping against fixed copper plates at the top and bottom generates charge transfer, thereby producing electricity. In COMSOL, I first attempted a fluid-structure interaction simulation by replicating the oscillating beam case from the COMSOL library. However, the calculation consistently diverges. Does anyone know how to configure this correctly? Kindly help me, thanks!
