摘要：

The present work describes the imaging of laser induced fluorescence (LIF) of formaldehyde in a high pressure/high temperature atmosphere. Gaseous dimethyl ether (DME) is injected at 70 bar into the combustion chamber. Formaldehyde is detected by its fluorescence from excitation using the third harmonic of a Nd:YAG-laser with a wavelength of 355 nm at chamber pressures of 20, 30 and 40 bar. The experimental results are compared to 1D flamelet simulation of the auto-ignition processes applying a detailed reaction mechanism for DME. The results reveal a very good accordance to the experimental findings.
