35-6 Flow Experimental Study in Scaling Model of Granular Spallation Target显示文摘The granular spallation target has been raised through theoretical calculation which is the crucial part of Accelerator Driven Sub-critical System (ADS)[1;2]. It is important to study the ow distribution inside of the spallation target before optimizing design. The experiments are carried out in a three-dimensional channel with a screw conveyor which using as granular drives.Liu Yang Qiang Chengwen Zhang Xueying Wang Fei Li Long Yang Weifeng 2015IMP & HIRFL Annual Report2015,,1:0
4Balancing QoE and Fairness of Heterogeneous Traffics Based on Equivalent Rate Scaling显示文摘With great increase of mobile service in recent years,high quality of experience(QoE) is becoming a comprehensive and major goal for service provider.To unify evaluations of different services,mean opinion score(MOS) as a subjective assessment is usually adopted for accurate and convincing reflection of user perceived quality.In this paper,we consider the effect of the burst transmission of best effort(BE) traffic on the uses with real time video traffic in the same cell.We extend the rate scaling process which was initially used to shape burstiness of BE users as interference to handle the scenario that BE users act as resource competitors with video users.A power reallocation strategy between the two types of users is presented and an algorithm further improving the fairness of BE users is proposed.The simulation results demonstrate that the proposed algorithm can not only promote the QoE of both types of users,but also guarantee the fairness among users.GAO Qiang FEI Zesong LI Na XING Chengwen KUANG Jingming 2015China Communications2015,12,1:0
55-13 Thermohydraulics Experimental Research Progress of Spallation Target显示文摘In order to verify the simulation results of the liquid metal target and the granular flow target, the spallationtarget laboratory have established several experimental benches and carried out some related experiments on thesebenches.1. Liquid Target ResearchA water loop has been established in 2012 for investigating the flow behaviors of water in windowless target andhas been rebuilt in 2014 for experiments of window target. The experiments are conducted in an approximately 1:1sized window target model shown in Fig. 1. The flow pattern inside the spallation area is visualized by means ofthe particle image velocimetry (PIV). The flow range of the present experiment is between 8.4 and 20 m3/h, andseveral typical flow patterns are observed under the conditions of different inlets and outlets.Yang Weifeng Zhang Xueying Qiang Chengwen Zhao Qiang Wang Fei Li Long Xu Xiaowei 2014IMP & HIRFL Annual Report2014,,1:0
65-14 Flow Field Measurement of Window Spallation Target显示文摘The spallation target coupling accelerator and subcritical reactor produces is key component of ADS[1??2]. TheLBE spallation target with window is popular because of its feasibility in last decades, but the target windowmaterial should bear beam radiations and liquid metal corrosions. A detailed study for the flow field of the targetconducted in an approximately 1:1 sized window spallation target model was carried out by visualization experimentsand numerical simulation. Water was used as the working fluid in the experiment. The flow pattern insidethe spallation area is visualized by means of the particle image velocimetry (PIV). The flow range of the presentexperiment is between 8.3 to 20 m3/h, several typical flow patterns were observed.Xu Xiaowei Qiang Chengwen Zhao Qiang Wang Fei Li Long Yang Weifeng 2014IMP & HIRFL Annual Report2014,,1:0
7Construction of a Performance Testing Platform for Granular Flow Heat Exchanger显示文摘The granular target was proposed as one of candidate for the ADS spallation target because of its own advan-tages[1-3].But it's just conceptual design,partial confirmatory experiments are highly necessary.Qiang Chengwen Li Long Wang Fei Zhang Xueying 2019IMP & HIRFL Annual Report2019,,1:0
8散裂靶实验组的研究进展显示文摘Accelerator Driven Subcritical System(ADS),which consists of a subcritical reactor with an external source provided by a high intensity accelerator through spallation reaction,has the ability of transmutation long life radioactive waste,breeding fission nuclides and produce energy.In 2017,spallation target experiment group has carried out some verified experiments for the ADS based on the VENUS-II zero power reactor and the prototype granular flow target,as well as the preliminary design report for the CiADS(China Initiative Accelerator Driven System)project.The detailed description of these works on the ADS is summarized below.Zhang Xueying Ma Fei Yang Weifeng Chen Liang Qiang Chengwen 2017IMP & HIRFL Annual Report2017,,1:0
