Porous Media Precise Reconstruction and Porosity Fluid Animated Simulation

In this paper we discuss how to precisely reconstruct porous media 3D model and simulate the fluid flow in the porous media. Considering the characteristics of the porous media's fault slice images, we present a contour extraction algorithm and based on the extracted contour we acquire the sandwich fault images. We modify the original MC algorithm with bounding box technology to accelerate the running speed, and the modified MC algorithm run faster when the pores are far away from each other. Current boundary treatment methods like boundary force method, ghost particle method and virtual boundary layer method, when dealing with complex boundaries, they will have to compute much on putting external particles. For resolving this problem, we propose a new method, and it handles the complex boundary very well. We use this new method to simulate the flow in porous media and analyse how the structure of porous media influence flow.
