摘要

The LBE is opaque,therefore,it is impossible to investigate the flow characteristic of fuel assembly in LFR by optical measurement techniques.Whereas,based on the dimensional analysis and similarity theory,by selecting reasonable model and working liquid,the results from experiment with the scaled model can be transferred to its prototype phenomenon,if the similarity conditions are fulfilled.The test section made from polymethyl methacrylate(PMMA)was designed to study the velocity field and pressure field.Many researchers have employed the refractive index matching(RIM)technique to match the RI of PMMA to obtain accurate,undistorted flow characteristics.However,many solutions in the literatures[1;2]can meet RIM purpose,but have the disadvantages of high viscosity,low stability,high toxicity and/or high cost for our experiment.
