Time-frequency hybrid multilevel feature alignment domain adaptation network for cross-condition fault diagnosis of rolling bearings

Traditional fault diagnosis methods suffer from performance degradation when applied under varying operating conditions. This presents a critical challenge to the analysis of industrial systems, where distribution shifts in sensor data severely degrade diagnostic reliability. Domain adaptation approaches have shown pro...

Unsteady flow characteristics and mechanisms of a centrifugal pump with impeller translation

This study investigates the influence of impeller translation on the internal flow of a centrifugal pump, with a focus on how translation-induced effects redistribute flow structures and modulate unsteady characteristics. Non-concentric impeller motion represents a critical off-design condition that exacerbates pressur...
