Gc. Wen et Lc. Chen, COMPLEX VARIABLE METHODS FOR THE SOLUTION OF SOME FILTRATION PROBLEMSWITH FREE BOUNDARIES, Arabian journal for science and engineering, 17(4B), 1992, pp. 605-609
This paper deals with two free boundary problems occurring in planar f
luid dynamics and axisymmetric filtration of nonhomogeneous anisotropi
c media, by using the complex variable methods, the existences of solu
tions for the above free boundary problems are proved.
