Keynote Speech I / 大會專題演講（一）
Title: Overview of Taiwan's Current Space Program: The Pivotal Role of Reactive and Plasma Device Development
Chair: Prof. Chun-Liang Yeh
Abstract:
In this talk, I will provide an overview of Taiwan's 3rd National Space Program (2019–2031), which encompasses three flagship satellite missions—optical remote sensing, synthetic aperture radar (SAR), and experimental low-earth orbit (LEO) communications—alongside the development of a domestic launch vehicle. A primary focus will be the progress and critical roles of reactive systems (including mono-propellant, bi-propellant, and hypergolic systems) and plasma discharge devices. Their specific applications in satellite Reaction Control Systems (RCS), rocket turbopumps, and both hybrid and liquid engines will be discussed. Finally, the talk will highlight the progress and the future prospects and strategic outlook for these technological developments.

Title: Plasma-Assisted Combustion of Carbon-Free Fuels
Chair: Prof. Shengyang (Steven) Shy
Abstract:
In view of the urgency of environmental problems such as global warming, energy demand, and pollutant emissions, there is a need for new combustion strategies. Plasma-assisted combustion (PAC) is one of them. It has attracted a strong interest from the scientific community for the last 15 years. The primary concept of PAC is to enhance combustion by mean of an electric field, using a minimum amount of energy and causing fewest pollutant penalties. Recently, PAC has been applied to facilitate the usage of carbon free fuels in existing combustion technologies. For example, it has been shown that PAC can improve the burning rate and combustion stability of ammonia flames, while reducing the amount of NOx released in the burned gases. However, these results were obtained for very specific conditions, and further work is needed to cover the range of operating conditions of practical systems. Another example is the ignition of ultra-lean hydrogen flames, in conditions relevant for spark ignition engines. Here again, PAC showed interesting results, highlighting the complexity of combustion physics. Recent findings and challenges in the field of plasma-assisted combustion of carbon free fuels will be discussed.
