Issues in Computational Studies of Turbulent Spray Combustion

Abstract

Turbulent spray combustion occurs in many technical applications such as internal engine combustion, gas turbine combustion, liquid-fueled rockets, and industrial burners. Major challenges are the modeling of detailed processes including the atomization process, the turbulent flow field, particle motion and interaction, chemical reactions as well as the strong coupling between these processes. The method of choice to achieve an integral model for the modeling and simulation of turbulent spray combustion is the detailed modeling of fundamental processes and simplification of these models before they enter a more complex tool. Thus, it is guaranteed that models are based on physical grounds and the degree of detailedness is sufficient to capture the essential features of the underlying process. The final tool then is based on physical grounds and it is not burdened with details not contributing to the main features of the flame structure.
