Fin Efficiency: pin#conical
4 to 5
Fin efficiency (eta) vs dimensionless parameter mL for straight, annular, and pin fins — rectangular, triangular, parabolic, and conical profiles
| pk | mL value | L definition | efficiency eta | fin profile | fin type | formula | geometry description | m definition | tip condition |
|---|---|---|---|---|---|---|---|---|---|
| pin#conical | 4 | pin length | 0.2338 | conical | pin | (1/mL)*I1(2mL)/I0(2mL) | Pin spine fin conical diameter tapers linearly to zero at tip | sqrt(4h/(k*D b)) where D b is base diameter | insulated |
| pin#conical | 5 | pin length | 0.1897 | conical | pin | (1/mL)*I1(2mL)/I0(2mL) | Pin spine fin conical diameter tapers linearly to zero at tip | sqrt(4h/(k*D b)) where D b is base diameter | insulated |
