This paper covers the characterization of the acoustic noise and the unsteady flow field of a high speed centrifugal compressor NASA CC3. In order to accurately predict the noise, all analyses are carried out through the ...

In the current study, a modified fast converging, mass-conserving, and robust algorithm is proposed for calculation of the pressure distribution of a cavitated axially grooved journal bearing based on the finite volume ...

Acoustic emission (AE) signal generated from defects in rolling element bearings are investigated using simulated defects and experimental measurements in this paper. Rolling element bearings are crucial parts of many ...

Particle Swarm Optimization (PSO) is a powerful nature-inspired metaheuristic optimization method that may determine optimal solutions of engineering problems in fewer evaluations compared to other optimization methods. ...

An optimization scheme that minimizes power loss and side leakage in journal bearings applications in turbines and other machinery operating in laminar flow is developed. The power loss equation is derived and shown to ...

The reliability of thermocouples with separation measuring junction in temperature measurement in the cooling process of hot steel plates with impingement jet has been investigated using direct and inverse finite element ...

A unified numerical treatment for handling various forms of constitutive relations for hyperelastic and rubber-like materials is presented. A general form for the stress and the constitutive tensors is derived. The form ...

Unidirectional dry gas seal may experiences reverse rotation when equipped in a centrifugal compressor. This paper describes how the reverse rotation effects on the spiral unidirectional dry gas seal performance and pressure ...
