AB  - In many geological structures, the permeability or penetrability of stone matrix is negligible compared
to stone fracture. In fact, fractures are the main direction of flow in stone massifs. As a result of improving the
efficiency of design studies; implementation of barefaced underground structures; separation of carbon dioxide
in underground brines; disposal of nuclear waste and investigation of the behavior of the current within the
fracture is considered as a crucial research project. The present study elaborates on a calculative model for
single-phase flow in a fractured environment in a special situation. The geometry of the fracture under study
is obtained through a series of Ct-scans from real fractures in Berea sandstone. The Ansys-Fluent Software
analyses the flow within a fracture with flow rate of 0.312-31.2 mm<sup>2</sup>/sec and width and permeability unit
of 500 mm Darcy and through application of pulse-sine input rate. Flow condition and pressure drop calculated
in this study are compared with a simulation of walls of an impenetrable fracture. The calculated fracture range
is produced through a two dimensional stone matrix. Furthermore, laminar flow is calculated for several input
rates. The pressure drop within the fracture is used to describe the relationship between flow rate and pressure
drop resulting from flow.
