Experimental study of hydrogen production using electrolyte nanofluids with a simulated light source
(Peer reviewed; Journal article, 2022)In this research, we conducted water electrolysis experiments of a carbon black (CB) based sodium sulfate electrolyte using a Hoffman voltameter. The main objective was to investigate hydrogen production in such systems, ... -
A concept of risk prioritization in FMEA analysis for fluid power systems
(Peer reviewed; Journal article, 2021)FMEA analysis is a tool of quality improvement that has been widely used for decades. Its classical version prioritizes risk of failure by risk priority number (RPN). The RPN is a product of severity (S), occurrence (O), ... -
Numerical investigation of a radially cooled turbine guide vane using air and steam as a cooling medium
(Peer reviewed; Journal article, 2021)Gas turbine performance is closely linked to the turbine inlet temperature, which is limited by the turbine guide vanes ability to withstand the massive thermal loads. Thus, steam cooling has been introduced as an advanced ... -
Prediction of buckling force in hourglass-shaped specimens
(Peer reviewed; Journal article, 2021)It is important to avoid buckling during low-cycle fatigue testing. The buckling load is dependent on the specimen shape, material properties, and the testing machine. In the present investigation of hourglass-shaped ... -
Computational study of the dissolution of cellulose into single chains: the role of the solvent and agitation
(Peer reviewed; Journal article, 2022)We investigate the dissolution mechanism of cellulose using molecular dynamics simulations in both water and a mixture solvent consisting of water with Na+, OH− and urea. As a first computational study of its kind, we apply ... -
A simple machine learning based framework for processing the inline inspection data of subsea pipelines
(Peer reviewed; Journal article, 2021)This paper presents a simple machine learning based framework for diagnosing the inline inspection data (ILI) of subsea pipelines. ILI data are obtained by intelligent pigging devices operating along subsea pipelines. The ... -
Local and global assessments of a subsea riser-spool connection under dropped impact loads
(Peer reviewed; Journal article, 2021)Subsea riser tube and spool is often used together to connect the riser of jacket to flowline or pipeline. Due to its limited size (less than 200 m), the location is within the lifting zones of the platform. Consequently, ... -
Performance of a tubular direct absorption solar collector with a carbon-based nanofluid
(Peer reviewed; Journal article, 2021)Direct absorption solar collectors (DASC) with nanofluid represent a new direction in solar thermal technology that is simpler yet more efficient than conventional equipment. In this work, we report details of performance ... -
Solar-driven desalination using nanoparticles
(Peer reviewed; Journal article, 2021)Due to the high light absorption and the possibility of localizing boiling to the interior of the receiver, nanoparticles are promising for solar-driven desalination. The paper presents an experimental study of the ... -
A Matrix FMEA Analysis of Variable Delivery Vane Pumps
(Peer reviewed; Journal article, 2021)Hydraulic systems are widely used in the aeronautic, machinery, and energy industries. The functions that these systems perform require high reliability, which can be achieved by examining the causes of possible defects ... -
Modelling of a bluff-body stabilised premixed flames close to blow-off
(Peer reviewed; Journal article, 2021)As emission legislation becomes more stringent, the modelling of turbulent lean premixed combustion is becoming an essential tool for designing efficient and environmentally friendly combustion systems. However, to predict ... -
Modeling Water Droplet Freezing and Collision with a Solid Surface
(Journal article; Peer reviewed, 2021)Water droplets released from the sea surface represent one of the major causes of ice accretion on marine vessels. A one-dimensional model of the freezing of a spherical water droplet moving in cold air was developed. The ... -
Soil Buffering Capacity Can Be Used To Optimize Biostimulation of Psychrotrophic Hydrocarbon Remediation
(Peer reviewed; Journal article, 2021)Effective bioremediation of hydrocarbons requires innovative approaches to minimize phosphate precipitation in soils of different buffering capacities. Understanding the mechanisms underlying sustained stimulation of ... -
