2. Benchmark solution#
2.1. Calculation method used for the reference solution#
The reference solution is the one recommended by Hughes and Brooks in their article cited as a bibliographical reference [bib1].
As an exact solution, we can take the temperature field from the upstream border projected onto the downstream border in the direction of the speed.

2.2. Benchmark results#
The temperatures are being tested on the border between points \(E\) and \(D\).

2.3. Uncertainty about the solution#
Analytical solution.
