Hello and thanks in advance!

I am attempting to model air flowing through a steel pipe using the chtMultiRegionFoam solver. I simplified the problem by making the temperatures of the air and pipe 300 K; however, the temperature of the air still increases as the simulation progresses.

Does anyone know why the temperature of the air would do this?
