Stainless steel 316 pin fins are designed for use in industrial cooling. The fins will be subjected to air flow at 20 m/s at T-350 K. Three fin geometries will be tested: V.T V.T V. T Configuration A Configuration B Configuration C Cross sections of cylindrical and square fins in cross flow All three configurations have the same cross-sectional area (the circular cross section has a diameter D= 12 mm) and all fins have the same length, L = 20 cm. Which fin has the largest heat transfer rate? If each fin is connected to a base with a temperature of 500 K and has an adiabatic tip, plot the temperature of each fin as a function of length from 0 to 15 cm. Note this problem requires you to first solve for the convection coefficient, and then review fin analysis.
