NUMERICAL INVESTIGATION OF PERFORMANCE OF AN AXIAL-FLOW PUMP WITH INDUCER

引用

Journal of Hydrodynamics 2007年第6期19卷 705-711页

作者： li yao-jun WANG Fu-jun College of Water Conservancy and Civil Engineering China Agricultural University Beijing 100083 China

The interaction of flow through the inducer and impeller of an axial-flow pump equipped with an inducer has significant effect on its performance. This article presents a recent numerical investigation on this topic. The studied pump has an inducer with 3 blades mounted on a conical hub and a 6-blade impeller. The blade angle of the impeller is adjustable to generate different relative circumferential angles between the inducer blade trailing edge and the impeller blade leading edge. A computational fluid dynamics code was used to investigate the flow characteristics and performance of the axial-flow pump. For turbulence closure, the RNG k-ε model was applied with an unstructured grid system. The rotor-stator interaction was treated with a Multiple Reference Frame （MRF） strategy. Computations were performed in different cases： 7 different relative circumferential angles （ Δθ ） between the inducer blade trailing edge and the impeller blade leading edge, and 3 different axial gaps （G） between the inducer and the impeller. The variation of the hydraulic loss in the rotator was obtained by changing Δθ . The numerical results show that the pressure generated is minimum in the case of （ G = 3%D）, which indicates that the interference between inducer and impeller is strong if the axial gap is small. The pump performances were predicted and compared to the experimental measurements. Recommendations for future modifications and improvements to the pump design were also given.

添加高效纤维素分解菌于农牧业有机冗余物中,通过有氧发酵制备出具有一定保水性、透气性和肥力的生物有机肥(MOF)。在乌拉特荒漠草原试验区进行MOF施加相关试验,施加量为1 kg·m^(-2)。结果表明,MOF的施加可以通过促进植被生长、改良土壤理化性质以及增加微生物数量等方式对退化荒漠草原植被-土壤-微生物系统起到快速恢复作用。其中,植被盖度增加了33%;土壤黏粉粒含量增加了2%,土壤全碳含量增加了9%,土壤全氮含量增加了0.9%;土壤细菌中11个门类数量变化差异显著,土壤真菌中1个门类数量变化差异显著;植被盖度增加的92%可由MOF的施加和土壤含水率共同解释,物种丰富度增加的84%可由MOF施加、土壤含水率和土壤电导率共同解释。试验结果为施加生物有机肥在干旱区荒漠草原产生的恢复作用提供了理论依据、数据支持以及技术支撑。

CFD SIMULATION OF 3D FLOW IN LARGE-BORE AXIAL-FLOW PUMP WITH HALF-ELBOW SUCTION SUMP

引用

Journal of Hydrodynamics 2006年第2期18卷 243-247页

作者： WANG Fu-jun li yao-jun CONG Guo-hui WANG Wen-e WANG Hai-song College of Water Conservancy and Civil Engineering China Agricultural University Beijing 100083 China

Numerical simulations of 3D turbulent flow in a large-bore axial-flow pump coupled with half-elbow suction sump were perlbrmed by using CFD approach. The numerical model and velocity and pressure distributions in entire flow passage were presented. The obvious backflow in half-elbow suction sump and strong flow nonuniformity at suction sump outlet were observed, whereas these phenomena were not observed in existing studies performed for a separate suction sump by either experimental or numerical approach. This result indicates that the interaction between half-elbow suction sump and impeller has significant effect on the flow distribution in the pump passage. The change of pump efficiency caused by the interaction was discussed,

BACKGROUND Waldenstr?m’s macroglobulinemia(WM) is a rare lymphoid neoplasia, which can have renal complications. These rarely occur, and most common renal manifestations are mild proteinuria and microscopic hematuria. Herein we describe a case of WM that presented with pseudothrombi depositing in capillaries associated with minimal change nephrotic syndrome and chronic kidney disease(CKD).CASE SUMMARY A 52-year-old man presented with features suggesting nephrotic *** workups were done, and there were elevated serum levels of interleukin-6 and vascular endothelial growth factor(VEGF), capillary pseudothrombus accumulation associated with minimal change nephrotic syndrome, CKD, and WM. Treatment was directed at the patient’s WM with bortezomib, thalidomide, and dexamethasone whereby serum immunoglobulin M(IgM) decreased. The damage of IgM on the kidney was corrected; thus, the patient’s proteinuria and serum creatinine had improved. The patient is still under clinical *** It is essential for clinicians to promptly pay more attention to patients presenting with features of nephrotic syndrome and do extensive workups to come up with a proper therapy strategy.
