STOCHASTIC FIELD SIMULATION FOR ORTHOTROPIC MEDIA

Flow Simulation in Stochastic Porous Media

Numerical simulation of stochastic PDEs for excitable media

We discuss the numerical solution of a number of stochastic perturbations of the Barkley model of excitable media, widely used for the analysis of spiral waves. Two numerical methods are considered for solving this equation, one based on Barkley’s original formulation and one based on spectral methods. It is found to be beneficial to modify the nonlinearity for the reaction equations. An effici...

T-spline based XIGA for fracture analysis of orthotropic media

Fracture analysis of orthotropic cracked media is investigated by applying the recently developed extended isogeometric analysis (XIGA) (Ghorashi et al., 2012) using the T-spline basis functions. The signed distance function and orthotropic crack tip enrichment functions are adopted for extrinsically enriching the conventional isogeometric analysis approximation for representation of strong dis...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Stochastic Simulation of Field Operations in Surveys

Discrete-event simulation modeling has become the most commonly used tool for performance evaluation of stochastic dynamic systems in science and engineering. The field operations of surveys can be classified as one of these stochastic dynamic systems. This paper describes the simulation and modeling of simplified field operations for NHIS (National Health Interview Survey). In particular, we a...
