Graphical Analysis of Fluid Flow Through Polymeric Complex Structures Using Multi-scale Simulations

Abstract

Efficient and detailed visualization of fluid flow simulations through complex meso-porous structures are fundamental for many applications in different areas such as medicine, biotechnology, oil recovery procedures, industry applications, environmental science and design of new intelligent and efficient meso-porous materials. Here we present the visual results of polymeric fluid flow through different complex porous media using multi-scale simulations performed over graphical processors (GPU’s). A Lagrangian numerical model known as Smoothed Particle Hydrodynamics (SPH) was used in order to simulate the flow through complex structures taken from real images or from other simulations which represents different porous media. Performance of the model and its visualization were analyzed for a regular and also for an irregular three-dimensional array of solid spheres that represents a porous media with different polymeric fluids. The comprehensive examination of different sections in the system help us to analyze in an improved way the dynamical behavior of fluids through sophisticated structures. Micro-channels built via mesoscopic Dissipative Particle Dynamics (DPD) simulations were also introduced with great detail and the flow through these micro-porous structures was analyzed in order to understand microvascular turbulent fluid flow. Detailed visualization in real time could be used not only to help in the study of different systems but also to obtain amazing images that would be impossible to achieve by other techniques, here we present some of this beautiful pictures.
