Welcome to Hyejeong!

Hyejeong Cheon started her PhD on August 19th, 2020 at PoreLab NTNU. Hyejeong holds a Master in Physics from NTNU. She holds a Bachelor in Nanobiomaterials Science and Engineering from Chung-ang University in South Korea, as well as a Bachelor in Physics from Umeå University in Sweden.

Her project at PoreLab is part of the project “PredictCUI: modelling to predict water liquid and vapor migration through porous media“. This project is financed by the Research Council of Norway.

Hyejeong presents her PhD project as follow: “Moisture migration in porous insulation layer from water penetration causes corrosion, so called Corrosion Under Insulation (CUI). In oil and gas industry, insulation layer surrounds pipes and it is observed frequently that pipes are corroded due to CUI. Corrosion is directly related to process efficiency and safety, so it is important to predict where CUI could occur.

Specifically, we will develop a mathematical model of water liquid and vapor (two-phase flow) transports in pore network to understand how and where CUI occurs. Study will be conducted on multi-scale modelling with the help of statistical mechanics, thermodynamics, fluid mechanics and numerical methods. Researchers including experimentalists from industry partners, NTNU EPT (Department of Energy and Process Engineering) and SINTEF will also collaborate in this project.”

Her supervisors are Alex Hansen from the department of Physics, NTNU and Øivind Wilhelmsen, Senior Research Scientist at SINTEF Energy Research.
