Abstract

This document presents a first approach to study the behavior of a static fluid radiated by infrared light (980nm,100mW) transmitted by a single-mode optical fiber, for this simulation temperature and radiation pressure are calculated based on the intensity delivered by a laser diode. The Computing Fluid Dynamics (CFD) results were based on a mesh Tet/Hybrid, TGrid for a Silica micro-particle and a mesh Hex/Wedge, Cooper for the beam. The results show that as the particle moves along the axis, temperature and pressure decreases, having the points of mayor temperature and pressure around the axis. The conclusion of this work is that it is possible to simulate the interactions between the beam, the micro-particle and the surrounding medium in terms of temperature, velocity and pressure using the energy and viscous model.
