Análise da formação de aerossóis de jato líquido em escoamento cruzado

Abstract

The understanding need of multiphase flow phenomena, as example of liquid jet breakup into droplets, has shown a constant adoption of Computational Fluid Dynamics (CFD) tools. Currently, CFD has been used widely in scientific research and engineering design optimization. This reality place the computational techniques to the tool class of cause and effect prediction. On the other hand, experimental setups are used to test and validate numerical and mathematical models. Based on this premise, the present work aims analyzing the capability and robustness of Taylor Analogy Breakup (TAB) model to predict spray formation and its properties in subsonic crossflow setting – condition where a liquid jet column are injected traversing a developed airstream. In the first step, a search of experimental data related to crossflow setting was realized to comparison and validation of simulated cases. UNSCYFL 3D (Unsteady Cyclone Flow 3D) was used in numerical simulations. This software has been developed in Fluid Mechanics Laboratory (MFLab). In the last step of this work, the preliminary results are presented and plotted in comparison with Phase Doppler Particle Analyzer (PDPA) data.
