About the position

The Department of Energy and Process Engineering (EPT) has a vacancy for a 3-year PhD scholarship on "Large Eddy Simulation for airflows inside buildings". The PhD work will be done in close collaboration between two research groups at EPT. The sustainable energy systems (SES) group has a strong experience in heating, cooling and ventilation systems in buildings, including building performance simulation (BPS). The thermo-fluids group has a broad focus on fundamental and applied research in fluid dynamics, including computational fluid dynamics (CFD) and turbulence modelling. The PhD work aims at taking advantage of the synergy between both research groups and disciplines.

 

The knowledge of building airflows is widely used to design high-performance buildings. In this respect, CFD is a powerful tool to study and predict airflows inside buildings. Nowadays, CFD in building is mostly performed using Reynolds-Averaged Navier Stoves (RANS) modelling and low-order numerical methods. However, both strategies are not optimal for building airflows. Therefore, the objective of this research work is to enable high-fidelity CFD in buildings using Large Eddy Simulation (LES) and high-order numerical methods. The PhD will focus on the flow physics and turbulence modelling specific to building airflows while the geometrical complexity will be kept relatively simple.

The main supervisor will be Associate Professor Laurent Georges (SES group). Co-supervisors will be Professors Bernhard Muller (Thermo-Fluids group) and Grégoire Winckelmans from UCLouvain in Belgium. The research group of Prof. Winckelmans is internationally recognized in the field of high-order methods and LES.

The position reports to Head of department Terese Løvås

Job abstractJV_description

A couple of challenging building airflows will be used to structure the research work, namely to

• Demonstrate the potential of LES in buildings.
• Better understand the physics of these airflows and create benchmarks for CFD validation.
• Identify how turbulence modelling and numerical methods should be adapted for these categories of flows.
• Adaptation of a high-order flow solver to integrate these modifications.
• Improvement of LES models (i.e. subgrid scale models) for airflows in buildings

Qualification requirements

PhD candidate:
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 Fluid Dynamics and CFD, 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.

The appointment is to be made in accordance with the regulations in force concerning State Employees and Civil Servants and national guidelines for appointment as PhD, postdoctor and research assistant

Other qualifications

• Prior knowledge (or experience) in LES or high-order methods is an advantage
• Extensive experience in programming (for instance in C)
• Proficiency in the GNU/Linux environment is an advantage
• Experience or willingness to use high-performance computing environment
• Excellent written and spoken English

Personal characteristics

• Interest in fundamental and multi-disciplinary research
• Strong analytical and organization skills
• Good collaboration and communication skills
• Willingness to perform a research stay at UCLouvain in Belgium

In the evaluation of which candidate is best qualified, emphasis will be placed on education, experience and personal suitability, as well as motivation, in terms of the qualification requirements specified in the advertisement

We offer

• exciting and stimulating tasks in a strong international academic environment
• an open and inclusive work environment with dedicated colleagues
• favourable terms in the Norwegian Public Service Pension Fund
• employee benefits

Salary and conditions

PhD candidates are remunerated in code 1017, and are normally remunerated at gross from NOK 449 400 before tax per year. From the salary, 2 % is deducted as a contribution to the Norwegian Public Service Pension Fund.

The period of employment is 3 years without required duties. Appointment to a PhD position requires admission to the PhD programme in Engineering, https://www.ntnu.edu/studies/phiv . 

As a PhD candidate, you undertake to participate in an organized PhD programme during the employment period. A condition of appointment is that you are in fact qualified for admission to the PhD programme within three months.

Appointment takes place on the terms that apply to State employees at any time, and after the appointment you must assume that there may be changes in the area of work.
