1. The agreement is very good for all the angles of attack except a cc o0 and 20°. In general, the distributions for u. 5°, l o0 and 15° show good agreement with the data, even adequately predicting the occurrence of pressure minirnums off of the leeward ray. For the larger angles of attack, the agreement breaks down in regions where it is evident that the effect of viscous phenomena should become important (see Figs. 6a - 6d). These comparisons (Fig. 3) indicate that source flow effects arising due to the tunnel's conical noz 7,le seem to be n,inin,al. In view of this, the reasons for the nonagreem.ent for the zero angle-of-attack ccise are not readily explainable.
