Facilities: Aerosol Shock Tube (AST)

The aerosol shock tube is able to measure pyrolysis and ignition delay in low-vapor-pressure fuels such as biodiesel and jet fuel. It is also the lab's primary facility for planar laser-induced fluorescence (PLIF) studies. Finally, the facility is used for studies of biological spore breakup at high temperatures and pressures.
