Abstract:
A novel semi-analytical method for calculating the characteristics of the flow in a porous medium bounded by a rectangular polygonal barrier is proposed. The method is based on the usage of Riemann theta functions. It allows one to effectively solve certain filtration problems with machine accuracy and obtain some characteristics of the solutions without solving the problem as a whole.
The work presented in Sections 1–5 is supported by the Russian Science Foundation under grant 16-11-10349. The numerical computations (Sections 6 and 7) were performed in the INM RAS Department of the Moscow Center for Fundamental and Applied Mathematics and supported by the Ministry of Science and Higher Education of the Russian Federation (agreement no. 075-15-2019-1624/2).
