Abstract
Turbulent diffusion phenomena are of practical importance with many engineering and environmental field (e.g., in the reactor design and the prediction of pollutant diffusion). In order to clarify turbulent diffusion field experimentally, it is useful to measure instantaneous concentrations of multiple species simultaneously in a turbulent flow. In the present study, measurement system for concentrations of two species using absorption method has been developed. Two laser diodes (LDs) with different wavelength are used as light sources; red LD (635 nm) and green LD (532 nm). Concentrations of mixture of two species premixed with various ratios are measured simultaneously. It is confirmed that the concentrations of two species can be measured precisely by the present measurement system.
