OverviewWe 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.

Assumptions 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

ResultsResistance q

Without fins on bottom 2.8 K/W 32 Watts

With fins on bottom 0.316 K/W 289 WattsFins on Side 58 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.
