Improving the Behavior Quality of Excitable Media Phenomena Using Recent Computational Tools
Journal Title: RECENT - Year 2009, Vol 10, Issue 27
Abstract
Nowadays, computational fluid dynamics (CFD) becomes more and more mature. Its software tools are increasing in importance, and constitute a great challenge for the research in this area. A modern area where CFD has large applications is the mixing theory. Since the years ’48, three basic stages were clearly identified in the study of the mixing: - The entrainment stage – where the large-scale flow structure need to be correctly described; - The subsequent stirring process (responsible for the interfacial surface generation between the mixing species) – where there is necessary, a correct defined intermediate range of scales; - The dynamic process – at the smallest scales – this must be captured to describe the molecular mixing process itself. The mixing problems are still far from complete solving. A recent goal is to find a consistent and coherent theory to stand up that a mixing model in excitable media leads to a far from equilibrium model. In this order, the present paper continues the recent work in the field of computational dynamics, bringing new useful features based on statistical and computational observations. The appliances of the software MAPLE11 are handled and their important applications for the study of the models' behaviour are pointed out.
