چکیده
Flexible gridding has the potential of increasing the accuracy in numerical simulation of ow through hydrocarbon reservoirs within limitations in computing time and memory space. This paper is devoted to the description of a computational algorithm for two-phase immiscible, incompressible ows in an adaptive composite grid. An IMPES approach is applied. The pressure equation is discretized on locally reened grids with nite volume scheme. To solve this equation, a FAC method outlined by McCormick is used. For the transport equation, we propose the nite diierence schemes : upwind are MUSCL. An object oriented programming language C++ is selected for the implementation. It provides a dynamic memory management and a convenient data structure for evolutive problems. Results for some examples illustrate the eeciency of proposed algorithm.
