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 ...
Soil-concrete interface properties subjected to temperature changes and cycles using direct shear tests
(
American Society of Civil Engineers Library (ASCE Library)
, 2017 , Conference Paper)
Geothermal foundations (energy piles) combine the structural function of deep foundations with the ground source heat exchangers to transfer geothermal energy to superstructures. The intermittent operation of the geothermal ...
Monitoring of simple linear quality profiles using dEWMA statistic under uncertainty of process deviations
(
IEOM Society
, 2019 , Conference Paper)
The quality of process or product is often characterized by the univariate or multivariate distribution of quality characteristics. The linear profiles are widely used to model the relationship between dependent and ...
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 ...
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. ...
Robotic Trains as an Educational and Therapeutic Tool for Autism Spectrum Disorder Intervention
(
springer link
, 2019 , Conference Paper)
Social robots are emerging to become useful assistive tools for use in the therapy and education of children with Autism Spectrum Disorder (ASD). The nature of ASD causes its symptoms and manifestations to vary widely, ...
Social robots and wearable sensors for mitigating meltdowns in autism - A pilot test
(
springer link
, 2018 , Conference Paper)
Young individuals with ASD may exhibit challenging behaviors. Among these, self-injurious behavior (SIB) is the most devastating for a person’s physical health and inclusion within the community. SIB refers to a class of ...

Aeroacoustic Simulation for NASA CC3 Centrifugal Compressor Operating at off Design Condition
(2016 , Conference Paper)
This paper covers the characterization of the acoustic noise and the unsteady flow field of a high speed centrifugal compressor NASA CC3. In order to accurately predict the noise, all analyses are carried out through the ...
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 ...
