Condition Monitoring of Helical Gears Using Acoustic Emission (AE) Technology

Hamel, Mhmod A. A. (Cranfield University, 2013-07)

Techniques such as vibration monitoring, thermal analysis and oil analysis are well established as means to have been used to improve reliability of gearboxes and extend time-to-failure. In this area Acoustic Emission ...
Defect source location of a natural defect on a high speedrolling element bearing with Acoustic Emission

Eftekharnejad, Babak; Addali, Abdulmajid; Mba, David (PHM Society, 2011-09-25)

The application of Acoustic Emission (AE) technology for machine health monitoring is gaining ground as powerful tool for health diagnosis of rolling element bearings. The successful application of AE to life prognosis of ...
Diagnosis of low-speed bearing degradation using acoustic emission techniques

Alshimmeri, Fiasael (Cranfield University, 2017-01)

It is widely acknowledged that bearing failures are the primary reason for breakdowns in rotating machinery. These failures are extremely costly, particularly in terms of lost production. Roller bearings are widely used ...
An experimental investigation into the correlation between Acoustic Emission (AE) and bubble dynamics

Husin, Shuib (Cranfield University, 2011-08)

Bubble and cavitation effects phenomena can be encountered in two-phase gas-liquid systems in industry. In certain industries, particularly high-risk systems such as a nuclear reactor/plant, the detection of bubble dynamics, ...
Heat removal in axial flow high pressure gas turbine

Alhajeri, Hamad (Cranfield University, 2016)

The demand for high power in aircraft gas turbine engines as well as industrial gas turbine prime mover promotes increasing the turbine entry temperature, the mass flow rate and the overall pressure ratio. High turbine ...
Monitoring Gas Void Fraction In Two-Phase Flow With Acoustic Emission

Addali, Abdulmajid (Cranfield University, 2010-04)

The two-phase gas/liquid flow phenomenon can be encountered over a range of gas and liquid flow rates in the chemical engineering industry, particularly in oil and gas production transportation pipelines. Monitoring and ...
Slug Velocity Measurement and Flow Regime Recognition Using Acoustic Emission Technology

Alssayh, Muammer Ali Ahmed (Cranfield University, 2013-07)

Slug velocity measurement and flow regime recognition using acoustic emission technology are presented. Two non-intrusive and three intrusive methods were employed to detect the slug regime and measure its velocity using ...
