Polytec is helping leading industry move the front of knowledge and develop new technology by advanced and applied research. The core knowhow utilized is within basic and specialised physic, mathematics and chemistry.
Polytec is leading R&D projects within Oil & Gas processing and transportation, CO2 transportation, corrosion, nanotechnology, maritime energy efficiency, wave/current and temperature modeling and much more.
Polytec currently employ 5 PhD candidates. All candidates are working to improve modeling tools used in the petroleum industry, where the impact will be better predictions and increased reliability. However, the results can be of significant interest in other fields as well.
1D gas pipeline modeling.
In the doctoral work the candidate has studied and evaluated the impact of:
- Coupling between momentum and energy equation
- Energy dissipation in the one-dimensional limit of the energy equation in turbulent compressible flow
- Unsteady heat transfer model between pipeline and surrounding soil
- Numerical solving schemes for 1D gas pipeline models
Oceanographic sea bottom temperature models.
The candidate works on methods for assimilating measurement data into oceanographic models. In addition the candidate studies the impact on the oceanographic models when it comes to light absorption from phytoplankton. The study can have a significant impact on the input data for subsea pipeline models, but the work will benefit everybody that makes use of oceanographic models.
Heat transfer modeling between pipelines and surrounding media, with a focus on buried pipelines.
Current heat transfer models usually assumes a steady-state between pipeline and ambient. The candidate aims at quantifying the impact of a full transient description of the heat transfer and to develop tools that allows this to be incorporated into pipeline modeling software. To compare model result with real data, the candidate has installed a measuring array around an operational pipeline to get detailed information of the temperature in the soil surrounding the pipeline.
CO2 leakage in Subsea Pipelines.
The candidate is creating a model for a subsea CO2 leakage with a special focus on the initial bubble burst. The result of this research will give valuable inputs to other plume models. The PhD work is part of a bigger project for which the main objective is to come up with procedures for how to handle a CO2 subsea pipeline leakage.
Topology of fracture network.
Accurate modeling of fracture networks is important to accurately be able to describe fluid flow in rock formation. As such fracture models play an important role in studies of groundwater movement, oil and gas recovery and CO2 storage. The PhD project uses network theory to investigate the properties of fracture networks and aims at improving models used to generate artificial fracture networks.
