Abstract: Vibration-induced high-cycle fatigue of blades is a prevalent issue in turbomachinery. Blade tip timing (BTT) emerges as a nonintrusive, promising method for assessing blade vibration. Despite its potential, BTT's inherent ...

Abstract: The fan is the main component of the cooling system of an automobile engine. A typical automobile cooling fan consists of a shrouded axial fan, stator vanes, a deflector, and a cover. With recent developments in the ...

Abstract: The aeroacoustic characteristics of a power module in the electric vehicle charging pile is studied by experimental and numerical methods. In the free field, a single cooling fan mainly emits tonal noise, while the far-field ...

Abstract: Blade tip timing (BTT) data are usually an under-sampled signal and are vulnerable to noise and sensor failures. In this paper, based on an arbitrary-angle compressed-sensing method and equiangular tight frame theory, ...
