A Review on the Gas‐Phase Modeling Study of Aluminum Combustion in Various Environments

Abstract

AbstractAluminum combustion is an area of intense research due to its wide‐ranging applications in the aerospace, automotive, energy storage carrier and defense industries. Gas‐phase reaction mechanism plays an important role on the prediction of the combustion intermediates and final products, which can significantly affect the combustion heat releases and combustion organization forms. In recent years, researchers have developed some gas‐phase reaction mechanisms to predict the combustion phenomenon and behavior of aluminum in different environments. This review aims to provide an overview of the current state of the art in gas‐phase modeling study on aluminum combustion with various oxidizers, including oxygen, steam, carbon dioxide and so on. The primary oxidation reactions of aluminum were concluded, and the rate coefficients of these reactions were also reviewed and compared in this work. Besides, the simulations by using the gas‐phase reaction mechanisms were reviewed and the main oxidation reaction pathways of aluminum with various oxidizers were analyzed based on modeling analysis results. Combining phase change reactions and surface reactions, gas‐phase reaction mechanism will become more important for prediction the combustion speed, combustion temperature and combustion mode of aluminum in future.
