An experimental study on the pressure drop in the circular tube was carried out under rolling condition, and the transient and time averaged data were obtained. The pressure drop calculation model under rolling condition was established and agreed well with the experimental data. The effect of rolling motion on the pressure drop characteristics was researched by analyzing the experimental and calculation results. It found that the cyclical fluctuation occurs in the transient total pressure drop, while the deviation of average total pressure drop is very small compared with static condition. By analyzing the transient total pressure drop and its composition, it is found that the friction pressure drop is almost constant under rolling condition; the additional pressure drop caused by rolling motion can be ignore; and the fluctuation of gravity pressure drop is the reason of total pressure drop fluctuation. © 2017, Editorial Board of Journal of Nuclear Power Engineering.

In order to address the problems of treatment of the deactivated commercial SCR catalysts (DSCR) used in coal-fired power plants and explore the potential of the MnOx-based low temperature catalysts, a new procedure was proposed. In the present procedure, the DSCR served as the catalyst support and MnOx was loaded on it by Multi-step impregnation method. The MnOx-based supported catalyst was used for NO reduction. Characterization of X-ray fluorescence, X-ray diffraction, scanning electron microscope, X-ray photoelectron spectroscopy and N2 isothermal adsorption were conducted to study the properties of the regenerated SCR catalyst. The results indicated that the regenerated sample (RSCR-II) with 4.67 wt% MnO2 on the DSCR exhibited the most superior NO reduction performance. In addition, the RSCR-II showed better NO reduction activity in a wider temperature range compared with that of the unpoisoned fresh commercial SCR catalyst. Two components, MnOx and unpoisoned V2O5, on the regenerated catalyst were responsible for the NO reduction. RSCR-II also exhibited excellent NO reduction efficiency at high gas hourly space velocity. Therefore, the proposed method can not only well regenerate the deactivated commercial SCR catalyst but also create a better SCR catalyst. © 2017 Chin. Soc. for Elec. Eng.

This paper presents a High Availability Application Service Platform (HAASP) and analyses its high availability. The architecture of this platform contains application server platform and high availability architecture. Application server platform consists of three major components, application release platform, which is implemented with WebLogic and WebSphere cluster, application and database platforms, which are built with Oracle RAC, and IBM Domino cluster. High availability architecture is constructed by virtual machines, distributed switches and storage pools. It employs virtualization technology to integrate physical servers and storages, where physical servers are responsible for the creation of virtual server cluster, distributed switches, storage pool and management of storages. Application server platform runs on the high availability architecture and our experiment result shows that HAASP, as a scalable and flexible architecture, could offer more persistent service compared with traditional application service platforms. © 2016 IEEE.

This paper presents a secure storage model named Peer to Cloud and Peer (P2CP). P2CP uses the cloud storage system as a backbone storage system. However, when data transmission occurs, the data nodes, cloud user, and the non-cloud user are involved to complete the transaction all together. The users, typically the client peers, can communicate with each other directly, thus bypassing servers on the cloud. Similarly, cloud servers can communicate with each other in a P2P mode. We also introduce a "hierarchy security" method to guarantee the data security in the proposed P2CP storage model. A key feature of our P2CP is that it has three data transmission tunnels: the cloud-user data transmission tunnel, the clients' data transmission tunnel, and the common data transmission tunnel. Assuming that the P2CP model follows the Poisson process or Little's law, we not only mathematically prove that the speed of P2CP is generally better than that of the pure peer-to-peer (P2P) model, the peer to server and peer (P2SP) model or the pure cloud model, but also testify the results through simulations. Beyond security, we also investigate the performance of another characteristic of usability of the data storage, namely availability, where P2CP is more robust to the failures of peers or servers in the cloud environment.

This paper presents a duplication-less storage system over the engineering-oriented cloud computing platforms. Our deduplication storage system, which manages data and duplication over the cloud system, consists of two major components, a front-end deduplication application and a mass storage system as back-end. Hadoop distributed file system (HDFS) is a common distribution file system on the cloud, which is used with Hadoop database (HBase). We use HDFS to build up a mass storage system and employ HBase to build up a fast indexing system. With a deduplication application, a scalable and parallel deduplicated cloud storage system can be effectively built up. We further use VMware to generate a simulated cloud environment. The simulation results demonstrate that our deduplication storage system is sufficiently accurate and efficient for distributed and cooperative data intensive engineering applications. © 2013 - IOS Press and the author(s).

In order to investigate the effect of thermal aging on mechanical-hardening behavior of CF8 cast stainless steel for reactor coolant pump (RCP) case material, static tensile experiments of the as-received and thermal aged CF8 steel at room temperature and 350℃ were carried out at a constant strain rate. The results show that the distribution of strain in the gauge length of the specimen is not uniform during tensile. With the increasing thermal aging time, the tensile strength of the steel gradually increases, but the elongation percentage changes reversely. The staged mechanical-hardening behavior of the steel at room temperature and 350℃ is observed and the n-values of each stage increase gradually during the deformation with the increasing thermal aging time, especially for the first stage. ©, 2015, Editorial Office of Transactions of Materials and Heat Treatment.

Absorption experiments were performed in a bubbling system to study the effects of four different organic amines on the wet flue gas desulfurization, while desorption experiments were conducted in an oil-bath heating device to analyze the desorption effects of the four organic amines. Results show that the desulfurization rate of above organic amines declines with the variation of time following the order below: piperazine > ethylenediamine > DEA > MDEA; whereas their desorption rate at same desorption temperatures increases with the variation of time, showing the desorption performance from strong to weak as follows: MDEA > ethylenediamine > DEA > piperazine. Through calculation with thermodynamic parameters, it is found that the Gibbs free energy of MDEA for absorption of SO2 is less than that of limestone, indicating that MDEA is a better desulfurizing agent, with stronger capability in SO2 absorption than limestone. © 2016, Editorial Department of Chinese Society of Power Engineering.

Experiments of visualized two-phase upward flow were conducted in the packed channel, which filled with 3, 5, 8 mm in diameter of glass sphere respectively. The gas superficial velocity ranges from 0.005 to 1.172 m/s. The liquid superficial velocity ranges from 0.004 to 0.093 m/s. Four representative flow patterns were observed as bubbly flow, cluster flow, liquid-pulse flow and churn-pulse flow, and corresponding flow pattern maps were also presented. It is found that the pulse flow region is dominant. The comparisons of flow pattern map between packed channel and non-packed channel show that the bubbly flow region in packed channel is narrower than that of non-packed channel due to the packing. The comparisons of flow pattern maps for three different packing sizes show that the cluster flow region expands with the increase of the packing diameter. In the low liquid superficial velocity, the cluster flow directly changes to churn-pulse flow in the packed channel with 8 mm packing.

This paper describes a hot model test of natural draft wet cooling towers (NDWCTs) to investigate the effect of cross walls on the thermal performance of NDWCTs under crosswind conditions. The hot model test can simulate the actual operation of a prototype tower by operating a model tower at steady state conditions while varying the temperature and flow rate of the incoming hot water along with the crosswind velocity. Cross walls of two shapes at different setting angles were installed in the rain zone and tested under various operating conditions. The results show that crosswinds degrade the NDWCT performance below a critical crosswind velocity Vcr, but improve the performance above Vcr. Increasing water flow rate and inlet water temperature can raise Vcr. Installing cross walls can improve the NDWCT performance. At low crosswind velocities, the solid wall leads to better NDWCT performance than the porous wall. However, the opposite effect is obtained at high crosswind velocities. At all crosswind velocities, the cross wall at a setting angle of 0° results in higher performance than that at 45°, regardless of cross wall shapes. Moreover, the cross wall at 45° degrades the NDWCT performance under high crosswind conditions. © 2011 Elsevier Ltd. All rights reserved.
