Contours of average velocity in the mid-plane Z=1. 100 contours levels taken between −0.25 and 0.86 for 〈u〉 and between −0.58 and 0.17 for 〈v〉. Dashed contours lines correspond to negative levels. a No SGS model 〈u〉; b No SGS model 〈v〉; c Vreman model 〈u〉; d Vreman model 〈v〉; e WALE model 〈u〉; f WALE model 〈v〉
