The Thermodynamics Laboratory is dedicated to the characterization of fundamental physics and chemistry in extreme and carbon-free pyrolysis/oxidation/combustion processes under transient and steady-state conditions with a variety of chemical and flow timescales. The laboratory is equipped with an Ultra-High-Pressure Rapid Compression Machine and a High-Pressure Plug Flow Reactor that are coupled with a high-repetition-rate time-of-flight mass spectrometry and a micro GC, respectively. These platforms enable probing the reacting dynamics and chemistry of gaseous, liquid and solid fuels at conditions representative of heavy-duty, gas turbine and rocket engines.
