Abstract

This study aims to extend the applicability of the complex variable boundary element method (CVBEM) to convective-dispersive flow in the presence of distributed fractures. It is difficult to model the behavior of detailed flow around thin objects such as fractures, owing to singularity at the object edges. In addition, when tracking streamlines that pass through fractures, one cannot identify the outward streamline corresponding to a specific inward streamline. This article shows how complex variables can be used to remedy these difficulties. It then proposes a numerical scheme for modeling potential flow in the presence of distributed fractures. The singular solution for flow around fractures is coupled with the CVBEM through singularity programming. Streamlines can be tracked through fractures by using the stream function. Another
