As the simulation time increases, indicating more radiative exposure to the outer tube wall, the higher temperature profiles move deeper diagonally to the left side of the wall. This phenomenon is clearly depicted by the change of colour from dark blue to the lighter blue and green at the major parts of the wall. At the end of 5 hr simulation, almost all sectors of the tube wall are heated to temperature greater than 20 oC. The targeted outlet stream temperature of 60 OC is achieved after the three-quarter end of the tube.
The usefulness of pdetool GUI in the enhancement of heat transfer teaching is indeed obvious. Average students that have difficulty in understanding PDE, let alone writing computer programs themselves, will appreciate the graphical outputs of the pde tool GUI. As they become more comfortable with the conceptual aspects, the students may be more enthusiastic about learning the mathematics and computer programming of PDE The MATLAB programming capability, the next step after mastering the pdetool GUI, is powerful and suitable or the purpose of this learning process.
