About us
The Department of Mechanics and Maritime Sciences (M2) conducts fundamental and applied research across all transport modes to achieve sustainable technological solutions. We offer and contribute to bachelor's and master's programs in areas like Shipping, Naval Architecture, Ocean Engineering, Automotive, and Mechanical Engineering. M2 fosters strong collaboration between academia, industry, and society for effective knowledge transfer. With an international environment, outstanding research, and world-class education, M2 consists of seven engineering and maritime science divisions, plus an administration and support division
About the research project
Motor sailing ships are key to meeting IMO's greenhouse gas emission reduction targets. By integrating sails, ships can reduce engine power usage, fuel consumption, and emissions - when combined with CO2-neutral fuels, there is a possibility to achieve fossil free shipping. Hard wing sails are a common wind propulsor, but optimizing their performance requires advanced sheeting strategies to prevent stall, a condition where sudden thrust loss occurs due to airflow separation. This project aims to develop an active flow control (AFC) system to enhance sail performance and mitigate stall effects.
We offer a postdoc position in active flow control for wingsail performance and operation. The goal is to develop innovative flow control techniques to optimize aerodynamic performance and reduce vibrations in unsteady metocean conditions. Prior research highlights the importance of stall conditions for optimal sail performance and safety, while also demonstrating the complexity of airflow around sails and ship structures.
To achieve this ojective, the project will combine scale-resolved CFD (PANS and LES) with experimental studies to analyze airflow near and beyond stall as well as around the hull. The postdoc will develop passive and active flow control algorithms, potentially incorporating machine learning/AI, to enhance aerodynamic performance and stall delay with rapid response times. The research is conducted in collaboration with KTH, the Royal Institute of Technology in Stockholm, where experiments and model-scale sea trials will take place. The team has well-established partnerships in wind-assisted propulsion and flow control research.
Who we are looking for
To qualify for the position of postdoc, you must hold a doctoral degree in a relevant field, awarded no more than three years prior to the application deadline.
You also have:
• Ability to work independently with strategic planning skills
• Creativity and hands-on problem-solving approach
• Solid interest in fluid dynamics, with ability in experimental and simulation work
• Interest in interdisciplinary collaboration and effective communication skills
• Motivation, curiosity, and a strong desire to further develop research, communication, and project management skills
The position requires sound verbal and written communication skills in English.
You are expected to be somewhat accustomed to teaching, and to demonstrate good potential within research and education.
• The date shown in your doctoral degree certificate is the date we use, as this is the date you have met all requirements for the doctoral degree. Exceptions from the 3-year limit can be made for longer periods resulting from parental leave, sick leave or military service.
What you will do
Your major responsibility as postdoc is to perform your own research in a research group. You will be guided by senior researchers at the involved departments and companies. The position may also include teaching on undergraduate and master's levels as well as supervising master's and/or PhD students to a certain extent. Another important aspect involves collaboration within academia and with society at large. The position is meritorious for future research duties within academia as well as industry/the public sector.
