b) Improvement of advanced laser diagnostics
Several experimental investigations on laminar and turbulent flames were demonstrated using laser scanning imaging and tomographic imaging of scalar and velocity field, briefly introduced as follows:
- 10 kHz tomographic OH-LIF imaging measurement for detection of auto-ignition ker-nels was performed on a methane jet propagating in a high-turbulent and high-temperature co-flow . The size and location of the detected kernels were evaluated for operating conditions with different Reynolds numbers of the fuel jet.
- Volumetric reconstruction of reaction zone on laminar and turbulent flames using sin-gle-shot tomographic OH-LIF imaging . The capability and feasibility of tomograph-ic OH-LIF were comprehensively evaluated in terms of illumination volume, number and orientation of detection views.
- First quasi-4D laser scanning imaging measurement was performed by using acousto-optic deflector (AOD). Flame topology visualization and velocity field measurements were demonstrated on a non-premixed turbulent lifted CH4 jet .
- Simultaneous species visualization and flow field measurements on a lifted DME jet flame using laser scanning CH2O LIF and tomographic PIV at 10 kHz.
