Numerical Investigation into a New Method of Non-Axisymmetric End Wall Contouring for Axial Compressors

Energies, 2022
To deal with corner separation in high-load axial compressors, this paper proposes a new end wall contouring method aimed at controlling the end wall secondary flow in more than one local area, generating a geometry with fewer control variables that is ...

Numerical Investigation of External Electromagnetic Field Coupling to Coplanar Waveguide [PDF]

International Journal of Industrial Electronics, Control and Optimization, 2020
In this paper, for the first time, effects of external electromagnetic fields on a coplanar waveguide (CPW) are numerically studied by means of the method of finite elements. Two CPW lines with different geometry and dielectric substrate permittivity are

Wind Direction Retrieval Using Spaceborne GNSS-R in Nonspecular Geometry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
A wind direction retrieval algorithm using spaceborne global navigation satellite system reflectometry (GNSS-R) in nonspecular geometry is presented. This article first focuses on investigating the influence of wind direction on the scattering strength ...
