Abstract

The combustion of liquid fuel sprays is one of the most popular energy conversion process in transport media. In the majority of practical applications, liquid fuels are composed by mixtures of different chemical components. This characteristic significantly increases the complexity of the physics underlying the spray combustion. To address it, the computational fluid dynamics becomes an indispensable tool. Analysis of the state of the art of the combustion of multicomponent sprays demonstrates that many improvements must be done to provide efficient and reliable tools for the industry. In view of this, a research proposal for the modeling of multicomponent spray flames in the context of the large eddy simulation coupled with the flamelet generated manifolds method is presented. Both techniques have been demonstrated great reliability and capability to address the combustion of single-component sprays. Therefore, both are part of the methodology comprised in this report. Attention is also given to the combustion of hydrous ethanol since it is relevant for the Brazilian industry. Specifically, this document consists in a post-doctoral fellowship project in cooperation with the Laboratory of Environmental and Thermal Engineering of the University of São Paulo and the Institute for Energy and Power Plant Technology of the University of Technology of Darmstadt (Germany), where the candidate successfully concluded his PhD work. The strong connection of both research unities and the topics involved in the PhD research of the present candidate turns this proposal quite promising. It is also important to highlight that this work aims to contribute to the ongoing FAPESP projects 2013/50238-3 and 2015/18029-0. (AU)
