| Abstract | |
Controlled transport of small amounts of fluids is critical for Lab-On-a-Chip, miniaturized systems of increasing use of chemical, biochemical, pharmaceutical and biological analyzes that tend to replace current analytical equipment. Micro-Devices are essential for controlled and accurate transport of fluids. However, a methodology for the calculation of fluid behavior in micro-devices has not yet been developed, and there is a demand for capable numerical models. This work presents the implementation of the Smoothed Particle Hydrodynamics (SPH) meshless method in the development of a 2D simulator for fluid flow problems in micro-devices. The simulator was programmed in the C/C++ language for CPU processing and CUDA-C language for GPU processing. The study of SPH formulation included phenomena such as surface tension, multi-phase, capillarity and wettability between fluid-fluid and fluid-structure. The steps of development of the computational simulator were: Review of non-mesh lagrangean particle methods eligible for modeling of fluid-structure interaction in micro-systems; Metology and formulation of constitutive equations for the description of fluid, structure and fluid-structure behavior using SPH; Implementation of micro-fluidic phenomena such as multi-phase (liquid-liquid) and surface tension and capillarity. All implementations of formulations and simulator validated by comparing results in literature and experimentation. Thus, the main objective of this work was to demonstrate SPH as a tool in the numerical modeling of fluids in liquid-liquid interaction and liquid-structure for the problems involved in microfluidic and micro-devices (AU) | |
