13.4.6 Postprocessing for Periodic Heat Transfer

The actual temperature field predicted by ANSYS FLUENT in periodic models will not be periodic, and viewing the temperature results during postprocessing will display this actual temperature field ( $T(\vec{r})$ of Equation  13.4-1). The displayed temperature may exhibit values outside the range defined by the inlet bulk temperature and the wall temperature. This is permissible since the actual temperature profile at the inlet periodic face will have temperatures that are higher or lower than the inlet bulk temperature.

Static Temperature is found in the Temperature... category of the variable selection drop-down list that appears in postprocessing dialog boxes.

Figure  13.4.1 shows the temperature field in a periodic heat exchanger geometry.
