Issue date:September 2011 Publication year:2011 Pages:74-78 Language:Chinese ISSN:10001298 CODEN:NUYCA3 Document type:Journal article (JA) Publisher:Chinese Society of Agricultural Machinery, No. 1 Beishatan Deshengmen Wai, Beijing, 100083, China Abstract:In order to prevent and eliminate vortex and the vortex tube occurred in the suction passage of two-way-reversible pumping system for the safe operation of the pump unit, an additional curved guide pier was placed on the bottom of suction passage under pump mouth. By using the CFD software the numeric simulation was made to obtain three-dimensional flow fields inside the pumping system with the additional guide pier and predict the performance of the pumping system. Combined with the model test, this paper focused on the velocity distribution of suction passage outlet, and its influences on the pump system performance. Both the computation and the measurement results showed that the additional guide pier on the bottom inside the suction passage did not effect on the velocity distribution of suction passage. The velocity evenness of suction passage outlet reach 93% with guide pier, which can meet the needs of pump operation. The performance of the pumping system was good and the high efficiency of the system at BEP is 68.89%. Experimental observations showed that the set of the guide pier could effectively prevent the vortex generation under pump inlet, the vortices were not found within the suction passage under different operation conditions. The pump ran smoothly without vibration. Comparing the calculated results with the model test results of the outlet velocity distribution of the suction passage, both of them are similar in overall structure and pump performance prediction at BEP is consistent with the test results.

Issue date:September 2011 Publication year:2011 Pages:634-640 Language:Chinese ISSN:10020446 CODEN:JIQIER Document type:Journal article (JA) Publisher:Chinese Academy of Sciences, 90, Sanhao Jie, Shenyang, 110003, China Abstract:A particle filter tracking algorithm based on multi-feature clustering is proposed. To address the issues such as the diversity of target features, the difference between methods of feature distribution description, and the arbitrariness of feature spatial structure, the multi-features representation of target model is unified into a clustering computing framework. The mean shift based feature space analysis approach is employed to adaptively calculate the clusters in any arbitrarily structured feature space. Based on the clusters, a target probability density estimation method, which is efficient and accurate, is proposed to represent the target model. The distance between the reference target and the candidate is calculated by the similarity measure of kernel density estimation, and is taken as important information for observation in particle filter system. To efficiently enhance the utilization rate of particles, an improved particle propagation model is presented. The object tracking experiments are performed on many real image sequences by using the LUV color features and the LBP (local binary pattern) texture features. Experiment results show that the proposed algorithm can obtain high tracking accuracy and strong robustness, meet real-time demand, and provide better tracking performance comparing with other typical algorithms.

Outlet circulation of the pump has great influence on resistance loss of flap gate, so the resistance loss and the square value of flow do not show the proportional relationship. In the conditions of the same flow, efficiency decreased value of pump system was negative correlated with the open angle of flap gate. On the basis of numerical simulation, flow patterns of the outlet were analyzed with and without flap gate under designed operating condition. The resistance loss of flap gate was predicted. A good agreement was achieved between the predicted data and the experimental data under designed operating condition.

Issue date:September 2011 Publication year:2011 Pages:406-410 Language:Chinese ISSN:16748530 CODEN:PAJIE2 Document type:Journal article (JA) Publisher:Editorial Department of Drainage and, 30 Mengxiyuan Lane, Zhenjiang, 212003, China Abstract:The operating region of axial-flow pumps is greatly reduced due to the existence of unstable operating range at low flow-rate condition. The energy performance of an axial-flow pump was measured in detail, and head-flow curve with bi-saddle was obtained. Particle image velocimetry (PIV) technology was used to measure the two-dimensional flow fields at the inlet axial plane under the flow rate of 0.73Qd, 0.55Qd, 0.43Qd and 0.33Qd. The experiment results show that backflow exists at the impeller inlet close to the wall, and the backflow zone increases with the decreasing of flow rate. With the decreasing of the flow rate, the turbulence intensity obviously increases, the turbulence intensity of axial velocity is higher than one of radius velocity and the turbulence intensity near the case wall is much higher close to the hub. The flow at the inlet wall evolutes from axial direction to circumferential direction can be seen clearly by the silk lines. The experimental results indicate that the lower performance of axial flow pump at the low flow rate condition is due to the unstable flow at the inlet impeller. This provides a reference for further improvement of axial-flow pumps performance at low flow rate condition.

Box 211, Amsterdam, 1000 AE, Netherlands Abstract:Brominated flame retardant (BFR), which containing in printed circuit boards (WPCBs), brings a series of environmental and health problems. Hydrothermal technology was applied to decompose brominated epoxy resin in WPCBs at subcritical or supercritical water conditions. The brominated epoxy resin was decomposed into oil and the environmental influence of BFR was eliminated. The experiment was carried out in a 5.7 ml tube reactor and heated by a salt-bath. The variation of degradation rate of brominated epoxy resin with reaction temperature, time and additives were studied. The compositions of liquid products were analyzed by gas chromatography-mass spectrometry (GC-MS). When reaction temperature exceeded 300 °C, retention time stayed over 30 min and alkaline additive existed, more than 80% brominated epoxy resin could be mainly decomposed into phenol, which can be used as chemical material. Two different hydrothermal decomposition pathways were discussed according to the characterization of products. The results indicated that brominated epoxy resin in WPCBs could be handled effectively by hydrothermal decomposition. © 2011 Elsevier B.V. All rights reserved.
