Abstract: LIF (Laser Induced Fluorescence) is a non-intrusive, whole-field and instantaneous measurement technique that has been applied in many measurement fields. Embarking from the present research situation, this work presents an introduction of principles and the early application of LIF technique to measuring visual mixing and concentration distribution, temperature fields and liquid film thickness. Analyzing the advantages and disadvantages of the technique, LIF technique can be used as the method of validation and verification of computational fluid dynamic (CFD) models. According to analysis of applicability, LIF technique has a wide range of application. It can measure the temperature fields and observe mixing phenomenon in the rod bundles, boron dilution in the downcomer and the liquid film thickness of containment. In conclusion, LIF technique can verify and validate advanced light water reactor simulation in the future.
