Hi,

I am Vishnu from india I am using comsol to do thermoacoustic modeling. I am trying to model thermoacoustic refrigerator. But I am having troubles with integrating thermoacoustic module with heat transfer module.

Vishnu,

Try using the heat transfer model (with porous structure) along with one of the options in the fluid flow module. I attached a simple thermoacoustic (heat engine) model where a closed-open tube with a porous plug with a heat source at one end.

Hi Munroe,

This case file gets some error for heat transfer porous material part when I open it. Have you finished an updated one?

Best regards,
Xingxing

Hi Xingxing Liu,

I see that you also worked on the modeling of thermoacoustics on comsol. I encountered some difficulties to do this modeling. if possible to be in contact for the exchange of informations.
