Fin Efficiency: straight#triangular
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 |
|---|---|---|---|---|---|---|---|---|---|
| straight#triangular | 4 | fin length | 0.2338 | triangular | straight | (1/mL)*I1(2mL)/I0(2mL) | Straight fin triangular profile tip thickness zero | sqrt(2h/(k*t b)) where t b is base half-thickness | insulated |
| straight#triangular | 5 | fin length | 0.1897 | triangular | straight | (1/mL)*I1(2mL)/I0(2mL) | Straight fin triangular profile tip thickness zero | sqrt(2h/(k*t b)) where t b is base half-thickness | insulated |
