AI Technical Summary
High-velocity simulations of the downstream horizontal pipelines in nuclear power systems are difficult to achieve under laboratory conditions, especially with a maximum velocity of 17 m/s, and the experimental equipment is also very expensive.
An atmospheric pressure visual downward horizontal pipe test system was designed, including a test section pipeline, a control pipeline, and an infrared thermal imaging monitoring system. By adjusting the cross-sectional shape and size of the pipeline, combined with visualization materials and various flow control devices, the flow velocity can be increased and the temperature can be precisely adjusted. The pipeline temperature information is obtained by using the infrared thermal imaging monitoring system.
Pipeline tests with a maximum flow velocity of 17 m/s were achieved under laboratory conditions, reducing equipment costs and labor input, providing observation conditions for turbulent infiltration length and eddy velocity distribution, shortening the test cycle, and obtaining detailed information on thermal cycling phenomena.
