Abstract:

The report, relating to blowing at the trailing edge in the presence of a wall, consists of two parts. In the first part, the possibilities of calculating the potential flow are examined, and two examples are dealt with, in which the profile and the jet are replaced by a line of velocity discontinuity, where the inclination of the jet is not necessarily small. The calculation is performed by rheoelectrical analogy. The second part concerns tests making visible the flow of water at low velocities over a wing with a jet normal to the plane of the chord. Subject to the laws of similarity, these tests permit the mechanism of the flow and the effect of the principal parameters to be determined. The development of the stagnation point observed during these tests agrees well with the results of a simple calculation made in the first part. Author
