Scott,

It would be cool (no pun intended) to see how heat dissipates through the air cooled fins. It could be as easy as applying a temperature to the inside surface of the cylinder and a heat transfer coefficient to the fins. You could also find out how much power is lost in heat. Also, it could be modeled with and without flowing air to see how hot the inside of the cylinder gets without air flow. Furthermore, you could do a transient model to see how long the engine can run without air flow before the inside of the cylinder gets too hot.

The hard part would be getting the cylinder wall material and aluminum cylinder properties just right. Also, the heat transfer contact gap between the cylinder wall material and aluminum cylinder would be almost impossible to estimate. However, if we know the actual inside wall temperature and average fin temperature with air flowing, the model could be confirmed.

You have a talent with SW. Thanks for sharing.
