We wanted to design a backpacking pot that would decrease cooking times using fins on the bottom and sides. This would decrease the amount of fuel needed and, thus, the weight a backpacker would need to carry.

 Constant temperature on the bottom  Reasonable surface and air temperatures  Averaged properties over the process  Fins modeled as isothermal, parallel plates  Fuel burning temperature  Radiation is approximately equal between the two cases, so it was neglected  Convection coefficient approximately equal between the two cases

Resistanceq Without fins on bottom 2.8 K/W32 Watts With fins on bottom0.316 K/W289 Watts Fins on Side58 K/W.22 watts  Fins on the side contribute very little. It would be best to not include them as the added weight is not offset by higher performance.  Fins on the bottom increase heat flux by a factor of nine, so they are worth the added weight.
