$NO_x$ Measurement of Exhaust Gas plasma by Laser Induced Fluorescence Spectroscopy
배기가스 플라즈마에서의 레이저유기형광법(LIF)에 의한 $NO_x$ 계측
Abstract
This paper describes preliminary discussions on spatial distribution of NO density, which is mostly contained in simulated NOX exhaust, between a wire-cylinder geometry discharge gaps by using Laser Induced Fluorescence(LIF) Spectroscopy. Spatial distribution of NO density will be measured with varying NO concentrations from 166 to 644[ppm] and diameters of central electrode from 6 to 10mm. Pulsed Nd:YAG laser, Optical Parametric Oscillator(OPO), and Frequency Doubler are used to excite NO molecules to their excited state.
