Question:

Consider a two-dimensional, straight triangular fin of length L = 50 mm and base thickness t = 20 mm. The thermal conductivity of the fin is k = 25 W/m· K. The base temperature is Tb = 50°C, and the fin is exposed to convection conditions characterized by h = 50 W/m· K, T∞ = 20C. Using a finite difference mesh with Δx = 10 mm and Δy = 2 mm, and taking advantage of symmetry, determine the fin efficiency, ηf. Compare your value of the fin efficiency with that reported in Figure 3.19.
