The objective of this modeling and simulation study was to establish the role of stress wave
interactions in the genesis of traumatic brain injury (TBI) from exposure to explosive blast. A …

This paper is concerned with determination of the acoustic pressure field in a centrifugal
pump. The main noise-generating mechanism is assumed to be the unsteady impeller blade …

This paper reviews modelling and interpretation advances of industrial fan stall phenomena,
related stall detection methods, and control technologies. Competing theories have helped …

This article reports on a full-scale structural simulation of flow-induced mechanical vibrations
and noise in a 5-stage centrifugal pump. An interior flow field is simulated by an LES-based …

This paper reports on an experimental investigation of large-scale flowfield instabilities in a
pump rotor and the process of noise generation by these instabilities. Measurements of the …

In spite of a low circumferential Mach number the sound of isolated centrifugal fan impellers
is sometimes dominated by distinctive tones at blade passing frequency (BPF) and integer …

Centrifugal compressor aeroacoustics are analyzed by means of a three-dimensional CFD
model. Three operating points at nominal compressor speed are simulated ranging from …

The possibility to detect unstable operating condition (stall or surge) of an automotive
turbocharger using vibration or acoustic measurements is studied. An experimental study is …

Radial impellers have several technical applications. Regarding their aerodynamic
performance, they are well optimized nowadays, but this is in general not true regarding …
