The University of Sydney,
Clean Combustion Research Group

The Clean Combustion Laboratory is located in the School of Aerospace, Mechanical and Mechatronic Engineering at the University of Sydney. It houses an extensive range of laser diagnostics methods for the measurements of velocity, mixing, temperature as well as reactive scalar fields in reacting and non-reacting flows. Our research in combustion is aimed at developing novel, clean and sustainable energy solutions that facilitate transition to a low emissions economy. We employ state-of-the-art lasers and cameras to probe turbulent flames and detect a range of relevant species such as OH, CH2O, NO, CO CH and PAH using techniques such as laser induced fluorescence.

This may be performed at low repetition rates of 10Hz as well as high repetition rates of up to 10kHz. Existing facilities include two low repetition rate (10Hz) Nd:YAG lasers (Spectra Physics, PRO-350) each providing an output of 1.4J/pulse at 532nm with a pulse duration of 9ns. These lasers can pump two existing dye lasers (Sirah, PrecisionScan, PRSC-LG-24-EG). Also available is a state-of-the-art high-speed LIF imaging system comprising two high-speed, Nd-YAG lasers (Edgewave, IS6II-E and HD30II-E) with a repetition rate of up to 10kHz and outputs of 3 and 12mJ/pulse, respectively. These can also pump two high-speed dye lasers (Sirah-Credo). The figure opposite show one Edgewave, 10kHz laser pumping a Sirah-Credo dye laser. Two reactive species, namely CH2O and OH were imaged recently using this set-up.
