Cohesive collisions of particles in liquid media studied by CFD-DEM, video tracking, and Positron Emission Particle Tracking
(Peer reviewed; Journal article, 2023)This paper investigates the cohesive collision of ice in an oil phase at temperatures ranging from −15.7 °C to −0.3 °C. The new information on the coefficient of restitution (COR) was obtained using three different velocity ... -
A comparative CO2 emission analysis of a diesel and electric engine
(Bachelor thesis, 2021) -
Comparing the identification of recommendations by different accident investigators using a common methodology
(Journal article, 2012)Accident reports play a key role in the safety of complex systems. These reports present the recommendations that are intended to help avoid any recurrence of past failures. However, the value of these findings depends ... -
Comparison of AUV hull designs using CFD and preparation for towing tank testing
(Bachelor thesis, 2020) -
A comparison of extreme mooring loads and response of a spar-buoy wind turbine using conditional waves
(Peer reviewed; Journal article, 2023)Three-hour random sea-state evaluations for ultimate limit state design of floating offshore wind installations are time-consuming and prevent the use of high-fidelity numerical methods from being implemented. In this work, ... -
Comparison of organic Rankine cycle concepts for recovering waste heat in a hybrid powertrain on a fast passenger ferry
(Journal article; Peer reviewed, 2018)The possibilities of recovering waste heat from the exhaust gas and other waste heat sources from a 900 kW fast passenger ferry Diesel engine by means of an organic Rankine cycle (ORC) were investigated. The recovered ... -
Computaions of a Bluff-Body Stabilised Premixed Flames Using ERN Method
(Peer reviewed; Journal article, 2022)Combustible carbon-based energy is still prevailing as the world’s leading energy due to its high energy density. However, the oxidation of these hydrocarbons disturbs the natural carbon cycle greatly by increasing greenhouse ... -
Computation of laminar hydrogen flames

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 ... -
Computational Study of Two-Phase Flow Morphology in a Nozzle
(Journal article; Peer reviewed, 2018)Multiphase flow meters are widely used in nuclear, petroleum and chemical industries. Here the flow rate is defined indirectly by the differential pressure measurement over the device. An additional measurement is required ... -

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), ... -
Concept proposal of a new oil distribution system for controllable pitch propellers
(Bachelor thesis, 2020) -
A CONTRIBUTION TO THE CURRENT DEBATE ABOUT THE ADEQUACY OF THE LINEAR-NO-THRESHOLD (LNT) MODEL FOR THE RISK RESULTING FROM RADON EXPOSURE
(Journal article, 2023)The Linear-No Threshold Hypothesis (LNT) states that risk from ionizing radiation is linearly related to dose with no dose threshold below which there was no risk. The LNT is an important fundament in practical radioprotection ... -
