Conventional ignition, via a spark, is achieved by significantly heating the gas. As the temperature is increased, the rates of chemical reactions increase until thermal runaway occurs, i.e., ignition. A spark is a thermal plasma, more specifically, a plasma that achieves high temperatures and is close to thermal equilibrium. In contrast, a cold plasma remains much cooler (room temperature) and can be far from thermal equilibrium. When a cold plasma is used for ignition, the chemistry is directly activated via electrons. Ignition via cold plasma can therefore be more efficient for combustion chemistry activation. In a plasma, electrons are accelerated via a user-applied electric field. Identifying optimal plasma conditions for the activation of combustion chemistry requires a thorough understanding of both plasmas and combustion. In this presentation, I will start by introducing the basics of plasma physics. After which I will introduce plasma chemistry and finally, plasma-assisted combustion is covered. As you will see, the introduction of plasma chemistry to combustion introduces several modeling challenges.
About the Speaker
Thijs Hazenberg obtained his master's degree at Eindhoven University of Technology (TU/e) in 2019. As part of the master's program, he did his internship at Rolls-Royce Deutschland, where he worked on the development of fuel injectors for aerospace engines. Afterward, he started his graduation project under the supervision of Jeroen van Oijen. His master thesis is about model development for metal flames. This work was awarded the NVV combustion award and the KNCV Golden Master Award. Directly after graduation, Thijs joined the Power and Flow group as a Doctoral Candidate. In this position, he is now working on model development for plasma-assisted combustion.
