An application of the dual integral equations for the flow through fissured rocks (Q1117794)

This paper is concerned with the class of unsteady, irrotational compressible flows through fissured rock, when the corresponding pressures and velocity components have axial-symmetric distributions of sources. The first object of this paper is to discuss in detail the flow with the free surface through the fissured rock under certain boundary conditions, using the dual integral equation method. Secondly, a combination of the integral formulas of Bessel functions, which facilities the physical interpretation of the results and renders possible the complete determination of the corresponding free surface is given.
