Critical loading, a key parameter for evaluating the limit of pressure rise in cascade, plays fundamental role triggering compressor stall. This work identifies specified vortex aggregation as primary mechanism driving critical which subsequently accelerates stall onset. Through 2.5-dimensional (2.5D) cascade and three-dimensional simulations, mechanisms are comprehensively analyzed. In 2.5D an increased angle attack alters trajectory shedding vortices, causing them to spread...
Direct current (DC) bias induced by the DC transmission and geomagnetically is a critical factor in abnormal operation of electrical equipment widely used field power distribution system state evaluation. As main affected component, vector magnetization transformer core under has rarely been studied, resulting inaccurate estimations. In this paper, dynamic hysteresis model that considers impact rotating DC-biased fields introduced into numerical analysis to simulate magnetic properties, iron...
To achieve a near-zero magnetic field environment, the use of permalloy sheets with high-performance properties is essential. However, mainstream welding processes for magnetically shielded rooms (MSRs), such as argon arc and laser welding, can degrade material. Additionally, neglecting anisotropy introduce unpredictable errors in evaluation MSR performance. address this issue, paper proposes modified model calculating shielding factor (SF) MSRs that incorporates anisotropic characteristics...
We report self-starting mode-locking in all-fiber erbium-doped lasers utilizing inkjet-printed transition metal dichalcogenide saturable absorbers, exhibiting highly optical uniformity, with <5% standard deviations.
