Design of a High Uniformity Laser Sheet Optical System for Particle Image Velocimetry

Autor: Kewei Yin, Jun Zhang, Shuang Chen

Publikováno v: Aerospace, Vol 8, Iss 12, p 393 (2021)

Particle image velocimetry (PIV) is a non-contact, instantaneous and full-flow velocity measurement method based on cross-correlation analysis of particle image. It is widely used in fluid mechanics and aerodynamics. Laser sheet optical system is one

Tectono-sedimentary analysis of the Lower Cretaceous succession in the sags of the Ondor Sum uplift, Southern Erlian Basin, NE China

Autor: Sheng Fu, Jiawang Ge, Hui-lai Wang, Ling Li, Kewei Yin, Xin Wang, Ning Tian, Zhen Liu

Publikováno v: Marine and Petroleum Geology. 124:104851

The tectonics of continental rift basins and the accompanying deposition processes are areas of increasing research interest. The Ondor Sum uplift is located in the southern Erlian Basin, NE China. It is a promising site for petroleum exploration. In

Tectono-stratigraphy characteristics of the Lower Cretaceous Saihantala Sag in the Erlian Basin, China: Normal faulting and controls on the depositional variability

Autor: Kewei Yin, Hui-lai Wang, Zhen Liu, Xin Wang, Jiawang Ge, Sheng Fu, Ning Tian, Hui Liu, Qi Han

Publikováno v: Journal of Petroleum Science and Engineering. 195:107840

Tectonism is one of the most important factors controlling the formation of sedimentary stratigraphy in lacustrine rift basins, but the controlling effects need to be further clarified. Based on 2D and 3D seismic data, well logs, logging data, and co

Accuracy improvement of interferometric Rayleigh scattering diagnostic

Autor: Shuang Chen, Furong Yang, Li Chen, Kewei Yin, Xiaobo Tu, Bo Yan

Publikováno v: AOPC 2017: Optical Spectroscopy and Imaging.

Cavity structure is used to increase the Interferometric Rayleigh scattering signal intensity. By using ZEMAX method, we simulate a special cavity mode comprising two spherical reflectors with different size, including the focal length and the diamet

Facile Preparation, Characterization and Photocatalytic Properties of Multifunctional BiFeO3 Nanocrystals

Autor: Liyong Wang, Yingjie Liu, Kewei Yin, Lei Liu, Yuanyuan Han, Xiaogang Cao, Guang Jial, Cuimiao Zhang, Chunzheng Wang

Publikováno v: Journal of Nanoscience and Nanotechnology. 11:5207-5209

Polycrystalline BiFeO3 nanoparticles (size 30-50 nm) were prepared by a simple microwave synthesis technique. The nanoparticles were characterized by XRD, TEM and TG-DTA. The applied experiments show that they are very efficient for photo-catalytic d
