is a concentric double tube exchanger.
correctly simulate the heat transfer (conduction) through the inner pipe from the internal fluid to the annular fluid.
Within the fluid, how convection from simulated temperature applications in the center which is higher up the temperature near the wall is lower?
convective transfer coefficient in the fluid is known, through the correlations.
in the input edge condition placed velocity (0.050m / s) and temperature (314 K).
