+As for the Navier-Stokes equations we see that the non-dimensional BGK equation is parametrized
+with an unique transport coefficient which is the Knudsen number. In the next episodes of this series
+we will make the link between the BGK and the Navier--Stokes equations and show how we discretize
+the BGK equation in order to simulate weakly compressible fluid flows.
