Numerical simulation and control of rotating stall in a transonic centrifugal compressor
(
Web Portal ASME (American Society of Mechanical Engineers)
, 2014 , Conference Paper)
This study presents a numerical simulation of precursors and characteristics of rotating stall in a centrifugal compressor with vaned diffuser. The aim is to further understand the causes of stall inception, characteristics ...
Systems engineering design of engineering education: A case of an embedded systems course
(
IEEE Education Society
, 2012 , Conference Paper)
Systems and Cybernetics can be found elsewhere in natural and engineering sciences. Control systems methods (technical cybernetics) are the nerve of the industrial revolution; they have recently penetrated some social ...
Development and evaluation of open educational resources for enhancing engineering students' learning experience
(
IEEE Education Society
, 2012 , Conference Paper)
The aim of this paper is to report on the development of control systems open educational resources. The paper reports on two control systems education software: 1) A LabVIEW based Control Systems Analysis Toolkit (CSAT) ...
Flow mapping of multiphase flows using a novel single stem endoscopic particle image velocimetry instrument
(
Institute of Physics Publishing
, 2011 , Conference Paper)
Particle image velocimetry (PIV) is a successful flow mapping technique which can optically quantify large portions of a flow regime. This enables the method to be completely non-intrusive. The ability to be non-intrusive ...
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. ...
An exploration into the religious and symbolic meanings of gendered spaces in an Arab gulf home
(2011 , Conference Paper)
Houses are rich symbols representative of culture, self and identity (Marcus 1995). The current research provides a comparative perspective on Arab-Islamic (Qatari) and Western values as encoded in the home and use of ...
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 ...
