Paper on vortex methods

Tanguy

Gooood morning, I am looking for two papers published 25 years ago:

1) Leonard, A. Vortex Methods for Flow Simulations, J. of Computational Physics, vol. 37, nb. 3, October 1980, pp.289-335.

2) Sarpkaya, T. Computational Methods with Vortices - The 1989 Freeman Scholar Lecture, J. of FLuids Engineering, Vol. 111, March 1989, pp. 5-52

If you have a copy of one of these papers, I would appreciated if you scan it and send it to me.

Cordially,

Tanguy
