The purpose of the present work is the development of Planar Laser Induced Fluorescence technique for temperature and concentration measurements in liquid phase of a two phase flow. The basis of technique PLIF are studied and two application are carried out:1-color PLIF and 2-color PLIF. A preliminar calibration is carried out to characterize the solution used and to study the influence of the dye as intrusive. The measurements are performed on a cell at homogeneous temperature and on the sprays. A particular setup is designed for applying the technique on the spray.
Data processing is developed to select the best technique between 1-color and 2-color and study the influence of some parameter on the accuracy of the measurements. Finally, further studies are suggested with regard to some parameters that could improve accuracy.
