Circular-Base Triangular Fin
Dimensional: eta_fin_spine_triangular(D, L, h, k)
Function eta_fin_spine_triangular calculates the fin efficiency of a triangular fin with a circular base. The function then calls a corresponding non-dimensional function, which determines the fin efficiency. Note that the fin surface area that should be used with this fin efficiency is:
Inputs:
L - length of the fin [m or ft]
D - diameter of the fin at the base [m or ft]
h - heat transfer coefficient [W/m^2-K or Btu/hr-ft^2-R]
k - conductivity of fin material [W/m-K or Btu/hr-ft-R]
Example:
L=0.075 [m]
D=0.005 [m]
h=60 [W/m^2-K]
k=200 [W/m-K]
eta=eta_fin_spine_triangular(D, L, h, k)
{Solution:
eta=0.8309}
Non-dimensional: eta_fin_spine_triangular_ND(mL)
Function eta_fin_spine_triangular_ND returns the fin efficiency of a triangular fin with a circular base given the product of the fin parameter, m, and fin length, L, where m is defined as:
