Om jobbet

Work Integrated Learning (WIL) is University West’s overarching profile and basic principle applied to learning, the exchange of ideas, and educational development. The government has assigned the distinguished task of developing WIL to University West. Work integrated learning in education and research develops new, relevant and advanced knowledge both within the academy and among its partners, which also benefits society in general. University West offers a wide variety of study programs, has a good number of applicants and the students show a high entry rate on the labor market. The main research environments at University West are Production technology, Learning in and for the new working life and Child and youth studies and is conducted in collaboration with the surrounding society. Campus is centrally located in Trollhättan with about 15,000 students and 625 employees.

Post doc in production technology – specializing in CFD applied to heat transfer and metal deposition in additive manufacturing process
The division of welding technology at University West is now looking for a post doctoral researcher with expertise in CFD modeling of thermal and multi-phase flow with free surface to study additive manufacturing with metal.

Role description

A main activity for the post-doctoral researcher will be to contribute to a multi-disciplinary research project aimed at investigating how to tailor the performance (functionality and integrity) of high strength/resistance steel components through two additive manufacturing processes, namely WAAM and LMDp. The post-doctoral research work will thus be conducted in collaboration with other researchers contributing to this project through expertise in process physics, metallurgy and p and control.

The post-doctoral researcher will work with the modeling and numerical computation of the additive manufacturing processes using the CFD software OpenFOAM® to investigate:

- The effect of the heat source and transferred metal on the temperature field and the thermal cycles of the deposited layer and its former underlying layers.
- The effect of the interlayer temperature (e.g. through the time elapsed between the deposition of two consecutive layers) on the temperature field and the thermal cycles of the deposited layer and its former underlying layers.
- The effect of the heat source and transferred metal on the melt pool geometry of the deposited layers.
- The effect of the active cooling or heating of the layer under deposition, or of some previously deposited layer, on the temperature field and the thermal cycles.

The research work will thus include:


- Proposing scientific methodologies according to project objectives.  
- Proposing and implementing further developments of the computational model according to project objectives.
- Conducting numerical simulations, evaluating and analysing the computational.
- Designing experiments to be used for model testing and validation; this will be done in collaboration with researchers in process development who will conduct the experiments according to project objectives.
- Writing and/or guiding students to write international journal manuscripts.
- Presenting results in project meetings and international Conferences.
- Supervising BSc and/or MSc students during their thesis project.
- Activly participating in the scientific and administrative meetings with the division of welding technology.
- Exploring collaborations to complement modelling and simulation capabilities at the university.

Qualifications

Candidates applying for the post-doctoral position should have a PhD degree in fluid mechanics, physics, or any other branch of engineering science if they possess appropriate experience in thermal fluid dynamics for multiphase problem, CFD simulation and interest in welding and additive manufacturing processes. The applicants who have obtained a doctoral degree or achieved the equivalent competence in three years or less prior to the end of the application deadline will be given priority.

The position also requires:


Skills in modelling and simulation of thermal flow with phase changes.
Skills in CFD with free surface deformation.
Experience of model development.
Advanced computer literacy and C++ programming skills.
Experience and interest in the presentation and publication of scientific results.
Ability for independent research as part of a team. 
Good command of the English language (speaking and writing).
Personal capabilities necessary to fully carry out the duties of the appointment in collaboration with the rest of the group.

The following skills will be considered meritorious:

- CFD with thermocapillary flow.
- CFD with electromagnetism.
- Knowledge and experience of OpnFOAM.
- Knowledge of welding, in particular of melt pool flow and metal transfer.
- Knowledge of additive manufacturing with metal, in particular of melt pool flow and metal transfer.
- Knowledge of the electric arc physics.
- Command of the Swedish language.
