摘要:
A laser-based measurement system has been developed that is capable of measuring the densities of all majority species. temperature and velocities simultaneously in turbulent hydrogen flames. The experiment aims on complete characterization of the instantaneous combustion situation in the probe volume. The measurement of these quantities is performed twice with a short time delay (µs-ems) using two iaser pulses. This double-puise technique is performed in order to monitor the temporal development of turbulent mixing and combustion. It is expected that the chain of cause and effect of mixing and combustion processes can be studied in detail by monitoring the situation over a sufficiently short time step. The novel measurement technique is discussed in detail and first experimental results arc presente
