Fins-2 (cont.)

T: adiabatic tip

Tc: convective tip

T(0.2)=87.32 °C

Tc(0.2)=87.09 °C

Note 1: Convective tip case has a slightly lower tip temperature as expected since there is additional heat transfer at the tip.

Note 2: there is no significant difference between these two solutions, therefore, correct choice of boundary condition is not that important here. However, sometimes correction might be needed to compensate the effect of convective heat transfer at the end. (especially for thick fins)
