Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason.

Rajesh Alayil

Hi Vivek,

It should be possible through enthalpy porosity model or solidification model.

please see the below link:

http://www.afs.enea.it/project/neptunius/docs/fluent/html/th/node349.htm

But, the challenge with out to simulate large discharging periods of PCM (computational resources and time).

Hope it helps you!

Thanks & Regards,

Rajesh.

Vivek Tiwari

Thank you for your reply. I am able to simulate solidification/melting using enthalpy porosity model but I am not able to find in how to model under cooling in ANSYS FLUENT user and theory guide.

Andreas König-Haagen

To my knowledge there isn't any CFD model that accounts for supercooling of PCM.

Kind regards

Andreas
