Numerical simulation of stall development into surge and stall control using air injection in centrifugal compressors
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
This study presents a numerical simulation of the formation of rotating stall and the initiation of surge in order to study the connection between stall and surge in centrifugal compressors. Also, the current paper introduces ...
Solving the inverse problem of crack identification using fuzzy genetic algorithms
(2010 , Conference Paper)
Failure due to low-cycle fatigue initiated cracks in rotating equipment may result in catastrophic scenarios. It is, therefore, important to identify fault parameters, such as crack size and crack location, to avoid such ...
Numerical investigation of steady air injection flow to control rotating stall in centrifugal compressors
(
Web Portal ASME (American Society of Mechanical Engineers)
, 2014 , Conference Paper)
This paper concerns the role of air injection method in stabilization and stall control in centrifugal compressors. The main aim is to find the best arrangement of air injection parameters such as injection angle and ...
Unsteady CFD simulation for high speed centrifugal compressor operating near surge
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
Centrifugal compressor surge and stall are an instabilities flow and system phenomenon, which can lead to a loss of engine power, large pressure transients and, in some cases, failure of the compressor and bearing system. ...
Tensile, hardness, and torsion behavior of welded AA
(
Trans Tech Publications Ltd
, 2014 , Conference Paper)
Tensile, Torsion, and Hardness behavior of welded and un-welded Aluminium Alloy 6061 T6 were investigated. Tests were conducted to evaluate the impact of tungsten Gas Arc welding (TIG) on some of the mechanical properties ...
Active control of noise in ventilation ducts
(
Canadian Acoustical Association
, 2019 , Conference Paper)
Ventilation ducts are often lined with passive absorption material for both thermal insulation and noise and vibration reduction. However, the noise reduction performance is not significant at low frequencies. Active Noise ...
Numerical simulation of one-stage gearbox dynamics in the presence of simultaneous tooth cracks
(
International Institute of Acoustics and Vibration, IIAV
, 2017 , Conference Paper)
Gears are vital components in various industrial machinery. Tooth fatigue crack is amongst the most common causes of gear failure. Early detection of tooth cracks is crucial for effective con-dition-based monitoring. This ...
Development of active acoustic noise cancellation using the professional audio development kit (PADK) featuring the TMS 320C6727 DSP
(
Springer Verlag
, 2017 , Conference Paper)
The PADK is a highly versatile DSP platform for implementing real-time audio applications. It features the Texas Instruments TMS320C6727, a powerful floating-point DSP processor and can process audio from eight input ...
Meta-heuristics for aircraft arrival and departure scheduling on multiple runways
(
Institute of Industrial Engineers
, 2012 , Conference Paper)
The problem of scheduling aircrafts on multiple runways can be modeled as an identical parallel machine scheduling with release times, target times and deadlines. To schedule arriving and departing aircrafts as close as ...
Heuristic algorithms for aircraft sequencing problem
(2012 , Conference Paper)
Delays in flights resulting in multi-billion-dollar losses are declared annually worldwide. Hence, an identification of air traffic policies that can reduce frequent and costly inefficiencies is needed. The problem of ...
