| 1 | Experimental Investigations of Micro Air Injection to Control Rotating Stall显示文摘在在第一个压缩机转子前面的尖端区域的稳定的分离微空气注射被证明了是一个有效方法处于低速度推迟旋转货摊的开始轴的压缩机。就实际申请而言,微注射者的一种新类型被设计并且在这描述了纸,它在 casing 是嵌入的并且能沿着弦被移动。为了验证它的可行性到另外的盒子,一些另外的盒子例如高亚声的轴的压缩机或离心的压缩机,被学习了。新注射者能拥有许多其它,这除成功地稳定压缩机以外有利的轴的压缩机显示出的一样的低速度的试验性的结果。当在片尖端的相对速度是高亚声的时,在一台高亚声的轴的压缩机上执行的实验证实了微空气注射的有效性。同时以便在离心的压缩机探索它的可行性,一个类似的微注射者与 vaned 在低速度上被设计并且测试离心的压缩机更弥漫。注射集体流动比在轴的压缩机和结果使用了那证明微注射能也在离心的压缩机推迟旋转货摊的发作的大一些。 | Chaoqun Nie Zhiting Tong Shaojuan Geng Junqiang Zhu Weiguang Huang | 2007 | Journal of Thermal Science2007，16，1： | 6 |
| 2 | Design and Optimization of a Single Stage Centrifugal Compressor for a Solar Dish-Brayton System显示文摘According to the requirements of a solar dish-Brayton system,a centrifugal compressor stage with a minimum total pressure ratio of 5,an adiabatic efficiency above 75% and a surge margin more than 12% needs to be designed.A single stage,which consists of impeller,radial vaned diffuser,90° crossover and two rows of axial stators,was chosen to satisfy this system.To achieve the stage performance,an impeller with a 6:1 total pressure ratio and an adiabatic efficiency of 90% was designed and its preliminary geometry came from an in-house one-dimensional program.Radial vaned diffuser was applied downstream of the impeller.Two rows of axial stators after 90° crossover were added to guide the flow into axial direction.Since jet-wake flow,shockwave and boundary layer separation coexisted in the impeller-diffuser region,optimization on the radius ratio of radial diffuser vane inlet to impeller exit,diffuser vane inlet blade angle and number of diffuser vanes was carried out at design point.Finally,an optimized centrifugal compressor stage fulfilled the high expectations and presented proper performance.Numerical simulation showed that at design point the stage adiabatic efficiency was 79.93% and the total pressure ratio was 5.6.The surge margin was 15%.The performance map including 80%,90% and 100% design speed was also presented. | Yongsheng Wang Kai Wang Zhiting Tong Feng Lin Chaoqun Nie Abraham Engeda | 2013 | Journal of Thermal Science2013，22，5： | 5 |
| 3 | The Response of a Low Speed Compressor on Rotating Inlet Distortion显示文摘在多线轴引擎,如果旋转货摊发生在在上游的压缩机,下游的压缩机经历旋转入口失真,它可以导致整个压缩机的不稳定性。在这份报纸,压缩机动态行为是主要焦点。实验在一台单个阶段的低速度的轴流动的压缩机上被执行。与不同失真部门装备的一个旋转失真发电机被设计顺时针方向或逆时针方向生产不同旋转入口失真与直到压缩机设计速度的 100% 。失真部门能被安装单个或在象四个部门那样的某联合一起。失真扇区 / 联合的三种类型在研究工作被使用,它是单身者 30 度部门,四 30 个度部门和单身者 120 度部门。失真速度什么时候升起,被发现总数迫使旋转部门增加引起的损失。为共同旋转失真,当失真速度对应于时,入口失真的所有三种类型在货摊边缘降级展出了一座山峰粗略地, 50% 转子加速。压缩机流动地的二维的数字模拟清楚地由失真部门显示出骚乱 trigged 的繁殖。关键词失真 - 压缩机 - 货摊边缘 CLC 数字 TK474. | Chaoqun NIE Jingxuan ZHANG Zhiting TONG Hongwu ZHANG | 2006 | Journal of Thermal Science2006，15，4： | 3 |
| 4 | A review on SRAM-based computing in-memory:Circuits,functions,and applications显示文摘Artificial intelligence(AI)processes data-centric applications with minimal effort.However,it poses new challenges to system design in terms of computational speed and energy efficiency.The traditional von Neumann architecture cannot meet the requirements of heavily datacentric applications due to the separation of computation and storage.The emergence of computing inmemory(CIM)is significant in circumventing the von Neumann bottleneck.A commercialized memory architecture,static random-access memory(SRAM),is fast and robust,consumes less power,and is compatible with state-of-the-art technology.This study investigates the research progress of SRAM-based CIM technology in three levels:circuit,function,and application.It also outlines the problems,challenges,and prospects of SRAM-based CIM macros. | Zhiting Lin Zhongzhen Tong Jin Zhang Fangming Wang Tian Xu Yue Zhao Xiulong Wu Chunyu Peng Wenjuan Lu Qiang Zhao Junning Chen | 2022 | Journal of Semiconductors2022，43，3： | 2 |
| 5 | Numerical Investigation into the Transient Behavior of the Spike-Type Rotating Stall for a Transonic Compressor Rotor显示文摘In this paper,a numerical investigation into a spike-type rotating stall process is carried out considering a transonic compressor rotor(the NASA Rotor 37).Through solution of the Unsteady Reynolds-Averaged Navier-Stokes(URANS)equations,the evolution process from an initially circumferentially-symmetric near-stall flow field to a stable stall condition is simulated without adding any artificial disturbance.At the near-stall operating point,periodic fluctuations are present in the overall flow of the rotor.Moreover,the blockage region in the channel periodically shifts from middle span to the tip.This fluctuating condition does not directly lead to stall,while the full-annulus calculation eventually evolves to stall.Interestingly,a kind of“early disturbance”feature appears in the dynamic signals,which propagates forward ahead of the rotor. | Pengfei Ju Fangfei Ning Zhiting Tong Jingying Wang | 2022 | Fluid Dynamics & Materials Processing2022，18，3： | 0 |
