Mechanical Engineering

Consider a circular (cylindrical) pin fin attached to a flatplane with the following properties:

k = 237 W/mC (thermal conductivity)

L = 100mm (length)

r = 2mm (radius)

T_b = 80 C (temperature at fin base)

T_inf = 20 C (air temperature)

h = 12 W/m^2C (Convection Coefficient)

Find the following using the infinitely long and insulated(adiabatic) tip methods:

The temperature of the fin at a distance L/2

Heat transfer rate from the fin

Fin efficiency

Fin Effectiveness

Thermal Resistance
