چکیده
Abstract Time-resolved absolute OH density measurements in a millisecond-pulsed DC glow discharge from carbon dioxide with water admixture, by laser-induced fluorescence (LIF) spectroscopy, are presented. For this purpose, novel technique is suggested to calibrate the LIF setup means of two-photon absorption spectroscopy on CO-filled gas cell. densities order 1 × 10 18 m −3 reported at pressure 6.67 mbar admixture 20% and current 50 mA. Furthermore, time evolution CO 2 conversion determined collision energy transfer validated against literature. The time-dependent rotational temperature obtained thermometry.

Absolute OH density determination by laser induced fluorescence spectroscopy in an atmospheric pressure RF plasma jet
In this paper, the ground state OH density is measured in high pressure plasma by laser-induced fluorescence (LIF) spectroscopy. The OH density determination is based on the simulation of the intensity fraction of fluorescence from the laser-excited level of OH (A) in the total detected LIF signal. The validity of this approach is verified in an atmospheric pressure Ar + H2O plasma jet sustaine...
متن کاملScalar Measurements by Laser Induced Fluorescence
This study is concerned with the measurements of scalar variables in turbulent flows, by Laser Induced Fluorescence. We used solutions of water and rhodamine B, to study the properties of the fluorescent tracer and the characteristics of the fluorescence signal and its dependence on the instrumentation and other experimental conditions. It is shown that a linear relationship between light inten...

متن کاملStudy of Geometrical-Dependence of Glow Discharge on Gain Coefficient in a TE-N2 Laser
Based on a set of experiments, using a transversely exited (TE) oscillator-amplifier N2-laser system (OSC-AMP) with the AMP effective length of 31cm, measurements have been carried out for small signal gain, g0, and saturation energy density, Es, for different AMP gap separations. It was found that the gain-value depends on the AMP electrode gap separation, d<su...
متن کاملMonitoring potential photochemical interference in laser- induced fluorescence measurements of atmospheric OH
In situ laser-induced fluorescence measurements of atmospheric OH are susceptible to interference from laser generated OH, particularly in the troposphere. To quantify this interference we implement the addition of perfluoropropene, C3F 6, for the chemical removal of OH from the ambient air. The removal rate of OH by C3F 6 is determined in the laboratory using the discharge flow technique. Over...
