Improving pre-turbine SCR systems in marine two stroke diesel engines using hybrid turbocharging: a numerical study of SCR operation range and system fuel efficiency
Nielsen, Jørgen Bremnes; Yum, Kevin Koosup; Pedersen, Eilif (Journal article; Peer reviewed, 2019)In this article, a performance evaluation of a novel system solution combining a hybrid turbocharger and a pre-turbine selective catalytic NOx reduction system is carried out. Pre-turbine selective catalytic system are ... -
Model Reduction through Machine Learning Tools Using Simulation Data with High Variance
Yum, Kevin Koosup; Pedersen, Eilif; Taskar, Bhushan (Journal article; Peer reviewed, 2019)Enhancing the computational speed through model reduction can facilitate the use of a complex system model for a design task. A part of the system model that is demanding in numerical calculation can be replaced by a ... -
Modeling and Simulation of Transient Performance and Emission of Diesel Engine: Pseudo Bond Graph Approach to Modelling the Thermodynamic Process
Yum, Kevin Koosup (Master thesis, 2012)Internal combustion engines have been very successful as power producers in the marineapplicaiton due to their simplicity of construction, high efficiency and long track of proven technology. However, as the environmental ... -
Open Simulation Platform – An Open-Source Project for Maritime System Co-Simulation
Smogeli, Øyvind Rasmussen; Ludvigsen, Kristine Bruun; Jamt, Levi; Vik, Bjørnar; Nordahl, Håvard; Kyllingstad, Lars Tandle; Yum, Kevin Koosup; Zhang, Houxiang (Chapter, 2020)The Open Simulation Platform (OSP) is an open-source industry initiative for co-simulation of maritime equipment, systems and entire ships. With steadily increasing complexity due to the increasing use of software in ship ... -
Transient Performance and Emissions of a Turbocharged Diesel Engine for Marine Power Plants: Numerical Simulation and Experimental Investigation
Yum, Kevin Koosup (Doctoral theses at NTNU;2017:237, Doctoral thesis, 2017)New marine power and propulsion plants have to meet increasingly stringent environmental regulations and requirements for flexible and efficient operations. Such a multi-objective task requires a systems approach in which ...
