Modelling of Soot Formation and Oxidation in Turbulent Diffusion Flames
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:175, Doctoral thesis, 2005)Soot and radiation play an important role when designing practical combustion devices, and great efforts have been put into developing models which describe soot formation and oxidation. The Eddy Dissipation Concept (EDC) ... -
Modelling project complexity
(Journal article; Peer reviewed, 2017)Purpose: The purpose of this paper is to enhance the understanding of what project complexity is, what drivers and factors that influence complexity and how consequences for organizational performance can be assessed. D ... -
Molecular Effects on Evaporation and Condensation
(Dr. ingeniøravhandling, 0809-103X; 2002:123, Doctoral thesis, 2002)In this thesis the evaporation from and condensation on a plane liquid surface have been studied by analysis and molecular dynamics simulations. The effect of the condensation coefficient on the inverted temperature gradient ... -
No fire without smoke : prediction models for heat release and smoke production in the SBI test and the Room Corner test based on Cone Calorimeter test results
(Doktoravhandlinger ved NTNU, 1503-8181; 46, Doctoral thesis, 2002)Smoke production in fire represents a threat because fire smoke reduces visibility and because fire smoke is toxic. One way to reduce the risk of persons being overcome by smoke during evacuation is by setting requirements ... -

(Dr. ingeniøravhandling, 0809-103X; 2001:84, Doctoral thesis, 2001)The present thesis deals with ultimate strength and collapse analysis of ship structures. Within this are, the attention is directed towards simple and efficient nonlinear finite element models for stiffened plate panels ... -
Norwegian natural gas transportation systems: Operations in a liberalized European gas market
(Dr. ingeniøravhandling, 0809-103X; 2001:34, Doctoral thesis, 2001)The main hypothesis tested in this work is: “It is possible to operate future Norwegian natural gas transportation systems at a level that is approximately optimal, technically and economically, with major stakeholders ... -
Numerical and Experimental Studies of Droplet-Gas Flow
(Dr. ingeniøravhandling, 0809-103X; 2002:111, Doctoral thesis, 2002)This thesis considers droplet-gas flow by the use of numerical methods and experimental verification. A commercial vane separator was studied, both numerically and by experiment. In addition, some efforts are put into the ... -
Numerical Investigation of turbulent Flow in a Channel with rough Walls
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:148, Doctoral thesis, 2004)Direct numerical simulation has been performed in order to study ressure-driven turbulent flow in a rod-roughened channel at Reynolds number Reτ = 400 (based on the mean pressure gradient). Square rods were attached to ... -
Ocean current Variability in Relation to Offshore Engineering
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:151, Doctoral thesis, 2005)This work adresses ocean current variability in relation to offshore engineering. The offshore oil and gas activity has up until recently taken place mainly on the continental shelves around the world. During the last few ... -
On State of Damage and Plasticity in pressurized layered Composite Tubes
(Dr. ingeniøravhandling, 0809-103X; 2003:10, Doctoral thesis, 2003)A method has been developed for the prediction of successive failure due to transverse cracking in wound composite layers and plastic deformation in isotropic layers of thick walled layered composite tubes. The model can ... -
On the shear capacity of steel plate girders with large web openings
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:9, Doctoral thesis, 2004)This report presents an investigation of the shear capacities of steel plate girders with web holes, penetrations, cut-outs or openings.
