Talk Title: Enabling Sustainable Propulsion and Clean Energy Transitions: Reacting Flow Modeling across molecular to continuum scales

Abstract: While the global demand for air travel continues to rise, the aerospace carbon footprint is increasingly concerning. In the near term, it is highly desirable for the rational design, efficient certification, and massive production of carbon-neutral fuels to mitigate greenhouse emissions. Furthermore, future aerospace vehicles will be integrated with highly efficient and high-speed propulsion devices using clean and renewable energy sources. The design of these sustainable and high-speed propulsion systems requires a fundamental understanding of reacting flow physics across multiple scales, featuring interactions between the molecular and the continuum flow scale.
In this talk, I will present state-of-the-art approaches to multiscale reacting flow modeling of sustainable aerospace energy carriers. The modeling spans from molecular scale using GPU-enabled quantum chemistry computation to continuum scale gas dynamics and turbulence-resolved flow modeling. I will first emphasize the reacting flow modeling of bio-derived sustainable aviation fuel (SAF), which is considered a near-term alternative to conventional jet fuels. I will then discuss the study of methane and natural gas as potential transition fuels, along with hydrogen and battery technologies for the long-term future. I envision that the presented approach will help not only to enable sustainable aviation but also to advance a clean and sustainable transition in the future energy landscape.
