This example models heated steam at a constant temperature of 120 C flowing through a aluminium pipe with 3 cm diameter. Heat loss to the surrounding cool air (at 25 C and heat transfer coefficient of h = 60 W/m2 C) is computed for a plain pipe, and also a pipe where 200 cooling fins per meter has been added. The simulation results are also compared with theoretical solutions [1].
The model is available as an automated tutorial by selecting Model Examples and Tutorials… > Heat Transfer > Cooling Effect of Adding Fins from the File menu. Or alternatively, follow the linked step-by-step instructions.
