摘要:

Experimental results were presented to visualize streak lines in a liquid metal by neutron radiography. Lead-bismuth eutectic was used as a working fluid for both natural and forced convention flows. Tracer and dye injection methods were employed for the visualization and the tracer made of gold-cadmium intermetallic compound and the dye made of lead-bismuth-cadmium alloy were developed. It was shown that both methods were applicable to a slow flow like natural convection and the liquid dye injection method and the tracer method were available to a fast flow
