Special Issue Information
Dear Colleagues,
With the recent advances in computational fluid dynamics, turbulence modeling, and computing power, numerical simulations of turbulent combustion involved in most practical applications utilizing energy conversion via combustion have been becoming a tangible task. The need for numerical simulations is ever increasing in various sectors of combustion applications such as IC engines, gas turbines for power generation and aviation, ramjet/scramjet propulsion systems, explosion and safety, and so on. In those applications, the primary goals of research and development are to improve energy conversion efficiency, to reduce emissions, and to avoid combustion instability. While the fidelity of numerical solutions for turbulent combustion is a crucial factor in such efforts, ascertaining the fidelity of any numerical simulations is still a very challenging task for researchers. There have been tremendous efforts in developing novel turbulent combustion modeling approaches seeking an optimal tradeoff between modeling accuracy and computational costs. As a result, researchers now have a wide variety of options, for example, between RANS, LES, and their hybrid, and among flamelet-based methods, conditional moment closure, and the transported PDF method, just to name a few. However, we still lack experience and data to come up with the best practices of numerical simulations in any applications.
This Special Issue is open to research and review articles of numerical simulations of turbulent combustion, focused on the practical applications and validation of any turbulent combustion modeling, in order to collect contemporary usages of computational fluid dynamics in the field of combustion science and engineering hoping to share between us insights on what the accomplishments, limits, costs, and room to further develop are in the field of turbulent combustion modeling and applications. In this sense, not only successful simulations but also failure stories are welcome to be communicated in this Special Issue.
