Mulighetsstudie av fornybare energikilder på skip
(Bachelor thesis, 2017)I dette mulighetsstudiet er det blitt sett på effektutnyttelsespotensialet til vind og sol-kraft og om hvorvidt disse ville kunne redusere klimagassutslippene til containerskip. Risiko forbundet med implementering av ... -
Multifuelforbrenning i store skipsmaskiner
(Bachelor thesis, 2002)Denne oppgaven er utarbeidet for vår oppdragsgiver Knutsen OAS Shipping A/S, som har planer om å bygge et skip som skal transportere komprimert naturgass. I denne forbindelse ønsker de en redegjørelse for mulige ... -
Multikonnektor for oppkopling av undervannsutstyr
(Bachelor thesis, 2006)Bakgrunn og overordnet beskrivelse av system / problemer med dette. Vi tar utgangspunkt i en sub-sea template for undervannsbrønner. På denne er det flere separate brønnslisser, som hver har et tradisjonelt ”juletre” ... -
Multimass disposal tool (MMDT)
(Bachelor thesis, 2009)RUE benytter seg kystdesigns ROV, ”Supporter” Dette er en kraftig arbeids ROV som har fått gode tilbakemeldinger fra sine brukere. ROV’er har de siste tiårene, mer og mer tatt over arbeidsoppgaver som tradisjonelt har ... -

Naturgass til kraftvarmeproduksjon
(Bachelor thesis, 2004)Hensikten med denne rapporten var å se på muligheten for bruk av naturgass til kraftvarmeproduksjon (Kogen) på Haugalandet. For å finne potensielle plasseringer for kogenanlegg har det blitt sett på to kundegrupper med ... -
Nedkjøling av stamfisk
(Bachelor thesis, 2002)I produksjon av laks tas stadig flere virkemidler i bruk for å manipulere tidspunkt for klekking og kjønnsmodening. Tidligere ble det utelukkende benyttet lysmanipulering for å endre på inntreden av disse tidspunktene. I ... -

NEW APPROACH TO IMPACT ANALYSIS USING THE MOVING FRAME METHOD THEORY AND NUMERICAL VALIDATION
(Bachelor thesis, 2019) -
A new method to determine the added mass of two- dimensional objects in potential flow.
(Peer reviewed; Journal article, 2022)The random walk source model is a displacement model where particles coming out of a source are displacing neighbor particles. The deformation of particle fronts moving towards objects carry the information about the fluid ... -

Novel Bio-compatible Tracers for Positron Emission Particle Tracking
(Peer reviewed; Journal article, 2020)To study the flow of objects in opaque flow processes, the PEPT (positron emission particle tracking) technique may be utilized. The PEPT technique is based on the same principle of positron emission tomography (PET). Both ... -
Numerical Analysis of an Articulated Hybrid Offshore Wind Turbine Concept
(Peer reviewed; Journal article, 2023)The concept of a "hybrid offshore wind turbine" originated from articulated loading platforms (ALPS). In this study, we have developed a concept design for the major structural components. Orcaflex was used to create a ... -
Numerical analysis of erosion due to nanoparticles in a pipe elbow
(Journal article; Peer reviewed, 2018)Flows of fluids laden with small particles in pipes are common in industry. An interesting and still unexplored issue is erosion of walls due to impact of particles. The main focus of our research was on nanoparticles. ... -
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 ... -
Numerical investigation of direct absorption solar collectors based on carbon black nanofluids
(Peer reviewed; Journal article, 2023)A novel model of a rectangular direct absorption solar collector (DASC) based on carbon black (CB) nanofluids for concentrated solar power is presented herein. Distributions of temperature, velocity, volume fraction of ... -
Numerical Modelling of Two-phase Flow in a Gas Separator Using Eulerian-Lagrangian Flow Model
(Peer reviewed; Journal article, 2021)Gravity-driven separators are broadly used in various engineering applications to remove particulate matters from gaseous fluids to meet legislation demands. This study represents a detailed numerical investigation of a ... -
Numerical models of multiphase flows with sticky particles
(Doctoral thesis, 2024)Plugging caused by adhesive particles remains an important problem in multiphase fluid dynamics for decades and needs extensive theoretical research. This work aims to investigate this problem using a coupled Computational ... -
