The topic of this thesis is damage of hydraulic machinery due to sand erosion. This is a very broad topic in which all the aspects of design of hydraulic machinery namely material selection; mechanics of material and ...

Ships and sea structures with a hydrodynamic perspective

Faltinsen, Odd Magnus (Journal article, 2022)

This article is about evolutionary design and freedom and is based on my new book, Freedom and Evolution: Hierarchy in Nature, Society and Science [1]. There is a lot to say about this broad subject, therefore I’ve reduced ...

Shock Tube Experiments on Nitromethane and Promotion of Chemical Reactions by Non-Thermal Plasma

Seljeskog, Morten (Dr. ingeniøravhandling, 0809-103X; 2002:67, Doctoral thesis, 2002)

This dissertation was undertaken to study two different subjects both related to molecular decomposition by applying a shock tube and non-thermal plasma to decompose selected hydrocarbons. The first approach to molecular ...

Silane Crosslinked Wood-Thermoplastic Composites

Bengtsson, Magnus (Doktoravhandlinger ved NTNU, 1503-8181; 2005:201, Doctoral thesis, 2005)

Wood-thermoplastic composites are a more environmental friendly alternative for pressure-treated lumber but can also replace engineering plastic products. These composites have been on the market for more than ten years ...

Simulations of Turbulent Flow between a Rotating and a Stationary Disk

Lygren, Magne (Dr. ingeniøravhandling; 2001:12, Doctoral thesis, 2001)

The main focus of this thesis is turbulent flow between a rotating and a stationary disk. The extension of the disks is assumed to be large enough to prevent the outer boundary conditions to influence the flow of the region ...

Slipforming of Vertical Concrete Structures. Friction between Concrete and Slipform Panel

Fosså, Kjell Tore (Dr.ingeniøravhandling, 0809-103X; 2001:61, Doctoral thesis, 2001)

Slipforming is a construction method that has been used in several decades for production of concrete structures. It is a wide range of different structures that are slipformed, but typical are vertical structures such as ...

Sloshing in rectangular tanks and interaction with ship motions

Rognebakke, Olav (Doktoravhandlinger ved NTNU, 1503-8181; 16, Doctoral thesis, 2002)

Sloshing is a violent resonent free surface flow in a container. The main objective of this thesis has been to study sloshing in rectangular and prismatic tanks. The tank may be excited by a harmonic motion or it may move ...

Smart production planning and control; concept for improving planning quality with production feedback data

Rahmani, Mina; Syversen, Øyvind; Romsdal, Anita; Sgarbossa, Fabio; Strandhagen, Jan Ola (Chapter, 2023)
