1. Pre-Processing

The layout of this case, PitzDaily. It is assumed the flat plate (thickness in Z-axis is 0.001[m]), with an inlet in the upper left.

2. Settings

Initially, temperature (T) is set to 1[K] and the flow velocity (U) is set to (10, 0, 0)[m/s].

5.1 Diffusivity

The following animation shows the difference of heat transfer (change of temperature) due to different thermal diffusivity. The upper case takes D=0.1 [m2/s], while D=0.01 [m2/s] for the lower case.
