Comparison of CFD Calculations with Experiments

A dramatic improvement in solution fidelity for DES compared to URANS, first reported by Shur et al. [‌22], was observed in the extensive cross-validation exercise carried out in the EU FLOMANIA project [‌4]. Figure 4 depicts the relative deviation from experimental drag achieved by DES and URANS within this work.

Figure 4: Comparison of URANS and DES for the prediction of mean drag coefficient for the NACA0012 airfoil at α = 60°. Results of 11 different simulations conducted by different partners with different codes and turbulence models within the EU FLOMANIA project [‌4]. Experimental data cited by Hoerner [‌6] are used as reference.
