Abstract

The liquid spray combustion is a process that can be found in various economic sectors, for instance: energy, transportation, and industry. It is indeed true that there is a growing tendency for the reduction of fossil fuel combustion, but the usage of the spray combustion process is a constant demand. Recently, the spray combustion has been demonstrated to be a fundamental process in novel technologies dedicated to the production of clean energy and new materials. Specific to the transportation sector, the spray combustion is a key process in energy transition technologies. However, the complexity associated with the underlying phenomena to the spray combustion, which is intensified when considering the multicomponent characteristic of liquid fuels, imposes many challenges to modeling techniques. To address this topic, the Computational Fluid Dynamics (CFD) is an indispensable tool. By reviewing the state of the art, a clear demand for improvements is noticed when considering the delivery of reliable and efficient tools to the industry and the academy. In view of such a demand, this project proposes the development of spray flame modeling techniques within the context of the Large Eddy Simulation coupled with the FGM (Flamelet Generated Manifolds) method. Both techniques have been used by the author of this proposal and are demonstrating great reliability and robustness to address the spray combustion of single component liquids. Attention is also given to the combustion of hydrous ethanol, which is an aspect that extends the scope of this work to multicomponent sprays. It is important to highlight that this project proposes a continuation of and a deepening into the topics previously addressed in the project FAPESP: 2017/06815-7. (AU)
