Fig. 15From: Compressible flow simulation with moving geometries using the Brinkman penalization in high-order Discontinuous GalerkinRotation of a fan composed by three NACA0012 airfoil profiles. The depicted pressure is normalized by the background pressure. The rotational movement is captured after: a 5s, b 10s, c 15s and d 20s. The normalized pressure is shown in the background. The streamlines (white) illustrate the velocity flow patternBack to article page
