Control of the combustion process and emission formation in marine gas engines
Krivopolianskii, Vladimir; Valberg, Ingebrigt; Stenersen, Dag; Ushakov, Sergey; Æsøy, Vilmar (Journal article; Peer reviewed, 2018)A smooth transition to the use of gas engines instead of conventional engines in marine shipping is a logical pathway for compliance with tightening environmental regulations. Currently, five major gas engine concepts are ... -
Experimental Investigation of Injection and Combustion Processes in Marine Gas Engines Using Constant Volume Rig
Krivopolianskii, Vladimir (Doctoral theses at NTNU;2019:96, Doctoral thesis, 2019)In circumstances of the strong demand for a reduction of harmful emissions from ships, one of the main pathways of the development of marine power plants is improvement of the existing and development of new gas engine ... -
Experimental Study of High-Pressure Gas Injection Using Optical Methods
Bredahl, Jens Kristian Myhrer (Master thesis, 2018)This thesis first presents the role of LNG as a potential means to reduce marine emissions and get international shipping into compliance with new regulations set by regulatory authorities. An overview of different gas ... -
Experimental Study of Ignition Delay, Combustion, and NO Emission Characteristics of Hydrogenated Vegetable Oil
Krivopolianskii, Vladimir; Bjørgen, Karl Oskar Pires; Emberson, David; Ushakov, Sergey; Æsøy, Vilmar; Løvås, Terese (Journal article; Peer reviewed, 2019)In this article, a comparative study of hydrogenated vegetable oil (HVO) and diesel was performed in two constant volume combustion rigs and an optical accessible compression-ignited chamber (OACIC). Ignition, combustion, ... -
Improvement of Thermodynamic Properties in Combustion Research Facility with Symmetrical Ignition Sources
Jaer, Peter Sommerseth (Master thesis, 2016)The Constant Volume Combustion Chamber (CVCC) at the Combustion Laboratory at the Institute of Marine Technology has shown: (I) Temperature related issues that reduce reproducibility within test series. (II) The environment ... -
Prognostics and Health Management for Air Compressors Based on Deep Learning Techniques
Gribbestad, Magnus (Master thesis, 2019)Typiske vedlikeholdsstrategier på luftkompressorer i dag er avhengig av planlagte vedlikeholdstiltak basert på levetidsstatistikk, eller å reparere noe etter det har feilet. Målet med denne oppgaven er å utforske prediktivt ... -
Soot Investigation on Fish Oil Spray Combustion in a Constant Volume Cell
Malin, Maximilian Christoph; Krivopolianskii, Vladimir; Rygh, Bjørn; Æsøy, Vilmar; Pedersen, Eilif (Journal article; Peer reviewed, 2015)Maritime environmental regulations stipulate lower emissions from the shipping industry. To cope with these rules, improving the combustion processes, make use of cleaner alternative fuels and implement exhaust gas cleaning ... -
Study of Compression Stages and Cylinder Arrangements for Reciprocating Air Compressor: A Modelling and Simulation Approach
Økland, Thomas Christian (Master thesis, 2023)En modell av en stempelkompressor er utviklet for å studere kompresjonstrinn og sylinderarrangement. Bond-graf metoden er valgt til å utvikle en to-sylindret stempelkompressor med fokus på det termodynamiske og mekaniske. Denne ... -
VERKTØY FOR DESIGNOPTIMALISERING AV EN STEMPELKOMPRESSOR
Høye, Herman; Stavdal, Øyvind; Vikra, Robin Holgersen (Bachelor thesis, 2023)Prosjektet fokuserer på utviklingen av et program som knytter sammen flere digitale operasjoner til én. Programmet kan endre material for kompressorens stempler og/eller endre geometri av en komponent. Det har her vært ...
