- Summary:
- The heat-transfer coefficients have been determined for five steel cylinders having fins 1.22 inches wide and the spacing between the fins ranging from 0.022 to 0.131 inch. The cylinders were tested were also tested enclosed in jackets with the cooling air supplied by a blower.
- A maximum heat transfer was reached at a fin space of about 0.045 inch for the cylinders tested with each of the three methods of cooling investigated. The rise in temperature of the air passing between the fins and the change in flow pattern were found to be important factors limiting the heat transfer that may be obtained by decreasing the fin space.
- The use of baffles for directing the air around the cylinders with closely spaced fins proved very effective in increasing the over-all heat-transfer coefficient provided that the spacing was not appreciably less than that for maximum heat transfer.
