摘要：
The article is devoted to visualization of the results of experimental work aimed at studying the turbulent flow of the coolant in the model of the lower chamber of a nuclear reactor. Using the method of tracer injection into one of the four loops of coolant circulation, we studied the mixing process of coolant flow in the lower chamber of the reactor. Based on the experiment, the values of the tracer volume fraction at individual points of the model are obtained. To visualize the results, the Matlab software package was used. Obtained during the processing of the experimental data, the tracer volume fraction fields in the characteristic areas of the lower chamber model made it possible to analyze the features of the motion and mixing of the loop coolant flows. The effect of swirling the coolant flow in the lower channel and in the lower pressure chamber of the model was experimentally obtained and visualized. © 2020 National Research Nuclear University.
