where Wch, Wf, Hf and g represent, respectively, channel width, fin
thickness, channel depth and fin efficiency. qb, which is the heat flux
from the heater to the working fluid, was obtained from a steadyflow
thermal energy equation with no changes in latent energy.
The average heat transfer coefficient is given by
For one dimensional heat conduction with adiabatic fin tip, the
fin efficiency is expressed by
