Numerical simulation of using combined active and passive stall control techniques in centrifugal compressors
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
This study presents a numerical simulation of stall control by using the casing treatment method which represents the passive control technique and also by using the air injection method which represents the active control ...
A novel technique for extraction of geothermal energy from abandoned oil wells
(2012 , Conference Paper)
This paper investigates the possibility of design and construction of a geothermal heat exchanger suitable for installation in abandoned oil wells. Based on the in-situ data collected, an amenable heat transfer numerical ...
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 ...
Numerical investigation of rotating stall characteristics and active stall control in centrifugal compressors
(
American Society of Mechanical Engineers (ASME)
, 2014 , Conference Paper)
This paper focuses on providing better view for the understanding of rotating stall phenomenon in centrifugal compressors by using numerical simulations and presents a study of the role of air injection method in delaying ...
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 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 ...
Toward 3D Printed Prosthetic Hands that Can Satisfy Psychosocial Needs: Grasping Force Comparisons Between a Prosthetic Hand and Human Hands
(
springer link
, 2017 , Conference Paper)
The advancement in 3D printing technologies appears to be the key toward affordable and functional artificial limbs. The loss of an amputee’s capability to do functional tasks like grasping objects has an obvious effect ...
Geothermal energy extraction from decommissioned petroleum wells
(
International Society for Rock Mechanics
, 2014 , Conference Paper)
Abandoned wells impose enduring liabilities to petroleum companies and/or governments. However, the depth and abundance of abandoned petroleum wells make them an economically attractive source of geothermal energy. Geothermal ...
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 ...
Multiple-runway aircraft sequencing problems using mixed-integer programming
(
Institute of Industrial Engineers
, 2012 , Conference Paper)
We examine aircraft sequencing problems over multiple runways, under mixed mode operations, with the objective of minimizing the total weighted tardiness of aircraft landings and departures. A mixed-integer programming ...
