PhD Position in Numerical Modeling and Simulation of Efficient Biocarbon Production
About the position
The Department of Energy and Process Engineering at the Norwegian University of Science and Technology (NTNU) is seeking a PhD student for the knowledge-building project for industry (KPN), “BioCarbUp”, funded by The Norwegian Research Council and industry partners. The project is lead by Sintef Energy, and involves several research institutions and industry partners. The candidate will be working in close cooperation with other PhDs and post-docs at EPT ComKin group, involved in similar activity.
Biocarbon (also known as biochar or charcoal) is a porous and carbonaceous solid made from biomass. The production of biocarbon usually involves heating biomass in the absence of oxygen or in lean oxygen conditions to a temperature above 300 °C with a residence time from minutes to days. During this process, hydrogen and oxygen are released from the biomass due to the dehydration and decarboxylation reactions.
Therefore, the resulting biocarbon has a very high carbon content (above 90 % on an ash-free basis). This makes the biocarbon an ideal reducing agent for metallurgical processes for example Si and FeSi production. Traditionally, fossil coal and coke are used as reductants resulting in large CO2 emissions from the metallurgical industry. The use of biocarbon as an alternative reductant can greatly reduce the CO2 footprint. However, it is very challenging to achieve a cost-effective and sustainable biocarbon production. Furthermore it is challenging to produce a product with the necessary mechanical characteristics for use in metallurgic processes. To address this, numerical modeling and computational fluid dynamics (CFD) simulation are chosen to gain insight of the conversion process of the biomass.
The head of the department is Professor Terese Løvås. The position’s day-to-day project management and supervision is by Professor Terese Løvås and Dr Tian Li.
Main duties and responsibilities
The objective of the PhD work is to develop CFD tools for simulating biomass carbonizer. The work involves studies of detailed kinetic models for biomass pyrolysis as well as investigations of interactions between biomass particle, fuel bed, and fluid flows inside the reactor. Additionally, special emphasis will be on improving computational efficiency by using either advanced numerical methods including statistical approaches such as principal component analysis or hardware acceleration such as GPU. Matching the experimental data with results from CFD simulations will be an important part of the PhD project. In this part, close collaboration with other research partners within BioCarbUp such as SINTEF Energy Research and Hawaii Natural Energy Institute will be crucial.
The PhD-position's main objective is to qualify for work in research positions. The qualification requirement is completion of a master’s degree or second degree (equivalent to 120 credits) with a strong academic background in chemical or mechanical engineering sciences or equivalent education with a grade of B or better in terms of NTNU’s grading scale. Applicants with no letter grades from previous studies must have an equally good academic foundation. Applicants who are unable to meet these criteria may be considered only if they can document that they are particularly suitable candidates for education leading to a PhD degree.
Motivation for fundamental scientific research of practical relevance is essential. Genuine interest in mathematical modelling and programming is a prerequisite, but direct experience with code development in C++, developing custom libraries or solvers with OpenFOAM, thermochemical conversion of solid fuels, CFD simulation of multiphase reacting flow, detailed chemical kinetic modeling, and GPU programming will be prioritized.
