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. ...
Mix and match: Collaborative expert-crowd judging for building test collections accurately and affordably
(
CEUR-WS
, 2018 , Conference Paper)
Crowdsourcing offers an affordable and scalable means to collect relevance judgments for information retrieval test collections. However, crowd assessors may showhigher variance in judgment quality than trusted assessors. ...
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 ...
Novel poly (diol-co-tricarballylate) implantable elastomeric matrices: Long term biocompatibility and biodegradation studies
