CPU hours of the reference solution (22M-None) and of the most relevant SGS models compared to the 6M-None for constant flow rate.

Mesh	SGS model	CPU h/6M-None CPU h	s/time step
22M	None	4.60	2.43
6M	None	1.00	1.58
6M	Sigma	1.77	2.80
6M	Dynamic Smagorinsky	2.66	4.20

There is a marked difference between the 22M and the SGS models. The amount of time required to perform each time step $\mathrm{\Delta }t$ highlights remarkable differences between Dynamic Smagorinsky SGS model and 6M-None
