Evolving Cellular Automata to Model Fluid Flow in Porous Media
نویسندگان
چکیده
Fluid flow in porous media is a dynamic process that is traditionally modeled using PDE (Partial Differential Equations). In this approach, physical properties related to fluid flow are inferred from rock sample data. However, due to the limitations posed in the sample data (sparseness and noise), this method often yields inaccurate results. Consequently, production information is normally used to improve the accuracy of property estimation. This style of modeling is equivalent to solving inverse problems. We propose using a Genetic Algorithm (GA) as an inverse method to model fluid flow in a pore network Cellular Automaton (CA). This GA evolves the CA to produce specified flow dynamic responses. We apply this method to a rock sample data set. The results are presented and discussed. Additionally, the prospect of building the pore network CA machine is discussed.

Coupled cellular models for biofilm growth and hydrodynamic flow in a pipe
In this paper we present a hybrid model for coupling of biofilm growth and hydrodynamic flow in a pipe. A cellular automata model, which is a discrete model, is used to describe the growth of biofilm. This stochastic discrete model is coupled with a continuum model of the fluid flow in a pipe. The potential applications of the proposed model are the flow in drinking water pipe systems or in aqu...
