Abstract

Abstract

In order to study the flow stability and applicability of the commutator with enclosed structure in the process of liquid lead-bismuth eutectic (LBE) medium commutation, FLUENT software combined with overlapping grid method is used to calculate and analyze the pressure and velocity fluctuations upstream of the commutator with enclosed structure in the form of three-way switching valve during commutation. The results show that in the process of commutation, the water hammer is produced when the valve element starts and stops, and the water hammer wave propagates in the pipe at the medium sound velocity, thus affecting the distribution of pressure and velocity in the pipe. The peak value of the water hammer wave is proportional to the medium density and the movement speed of the valve element, and the frequency of the water hammer wave is not affected by the movement speed of the valve element. Because the peak value of the water hammer wave is large, it is difficult for the upstream pipe of this type of commutator with enclosed structure to maintain a steady flow and threaten the safety of the device during commutation operation under LBE, so it is not suitable for LBE flow calibration device.
