“…A two-part flow map was included in the model to compute the medium void fraction of the gas pumped in the riser parts of the trial circuit, which is efficient for improving the circulation of liquid metals. Additionally, [ 80 ] analysed the potential for implementing gas-lift pumping using the natural circulation loop to improve LBE natural circulation. The consequence of raising the riser height at the upper portion of the gas injection point on the LBE natural circulation was also studied and found to have improved the natural circulation.…”

A pneumatic lifting pump is used in sewage treatment, offshore oil production, and other fields because of its simple structure and strong practicability. In order to study its internal hydraulic characteristics and gas-liquid two-phase flow, this paper carries out experimental research on the influence of different air intake modes and riser diameters on the performance of a pneumatic lifting pump. The air-water two-phase flow pattern in the riser and motion characteristics of bubble formation at the nozzle are obtained by a high-speed camera. Through theoretical analysis, the theoretical model of a pneumatic lifting pump is established, and experimental results verify the theoretical model well. The results show that when the submergence ratio is constant, the lifting efficiency decreases with the smaller intake area under different intake areas; and the influences of different holes distributions on liquid flow rate and lifting efficiency are not significant under the same intake area. At the same submergence ratio, the smaller the riser diameter, the smaller the final lifting liquid flow rate and the larger the lifting efficiency peak value.

“…In 2018, Lu et al 16 designed and did numerically studied on a centrifugal LBE coolant pump for SVBR reactor, and tested the performance of the pump based on water. Shi et al 17 experimentally investigated the gas lift pump for the lead‐bismuth eutectic loop by natural circulation capability loop (NCCL) test facility. Those studies about lead/LBE pump are concentrated on different new conceptual designs, while coolant flow velocity and performance optimization for lead/LBE pump is rarely reported.…”

Summary Lead or lead‐alloy‐cooled fast reactors (LFRs) have been proved to be the most promising generation IV reactors with high performance in neutron economy, thermal hydraulics and security features. When lead‐bismuth eutectic (LBE) is used as coolant for LFR, the primary LBE pump is a key conveying equipment in LFRs, because it pumps liquid LBE to remove decay heat produced by core. The hydraulic performance and coolant flow velocity of LBE coolant pump is of great importance for the safety aspects concerning LFRs. This study aims to design an axial LBE pump firstly based on the theory of planar cascade and streamline method, then establishes three‐dimensional model of the axial LBE pump and performs the simulation analysis based on Ansys CFX software to study the impact of design parameters on LBE pump hydraulic performance. The results show that the highest flow velocity occurs at the blade of pump and it increases with the rotating speed, while the pump efficiency and pump head appear up‐down tendency as the flow rate increasing. The optimum rotating speed and the corresponding impeller parameters are proposed based on the theoretic and numerical studies. The research work will provide a theoretical basis and referred solution for the design of primary pump small module LFRs.
