+\section{Reynolds number}
+The Reynolds number is defined as
+\begin{align*}
+  \Rey = \frac{u d}{ν} ⇒ u = \frac{\Rey ν}{d} = \frac{\Rey}{500}.
+\end{align*}
+In the default case $d = \SI{2}{\metre}$, $ν=\SI{e-3}{\square\metre\per\second}$.
+The inflow velocity is chose in a way that the desired Reynold numbers are reached,
+see table \ref{tab:values}.
+% and $u = \SI{10}{\metre\per\second}$.
+% So $\Rey = \num{2e4}$
