Mission
- The Unsteady Flow Diagnostics Laboratory (UNFoLD) led by Prof. Karen Mulleners at EPFL in Lausanne is looking for a PhD student to experimentally study the role of non-uniform bending stiffnesses created by vein-like patterns on the fluid-structure interaction of flapping flags in steady and unsteady winds in the framework of SNSF-funded project **_Morphlag._**
- Main duties and responsibilities
- Nature is full of thin, flexible objects that bend, flutter, or flap in the wind or the water due to fluid-structure interactions. Past studies on fluid-structure interactions have predominantly focussed on thin rectangular flexible sheets or filaments in steady winds. Few investigations have focussed on the influence of morphology and the effect of unsteady flow perturbations on the flapping dynamics of thin, flexible objects. In this SNSF-funded project **_Morphlag_**, we propose a paradigm shift in conducting unsteady fluid-structure interaction measurements to close these gaps. We will develop an intelligent automated experimentation pipeline to fundamentally study how fluid-structure interactions of cantilevered flexible sheets or flags depend on their morphological design. The project's ultimate goal is to set a benchmark for unsupervised experimental aerodynamic investigations and optimisation studies and demonstrate the approach by revealing new physical insights and discovering new scaling laws describing the dynamics of flags with arbitrary shapes and non-uniform bending stiffness through venation in steady and unsteady winds. These novel physical insights can inform the future design of agile and efficient bio-inspired propulsion systems and novel energy harvesting solutions using flexible plates or kites.
- Your responsibilities:
- Perform original research on how flags with different non-uniform bending stiffnesses created by vein-like patterns react in steady and unsteady winds.- Lead and contribute to publications in scientific journals.- Contribute to general lab activities (including teaching assistance and co-supervision of student projects)
- Profile
- A master's degree in engineering, environmental sciences, or physics.
- Strong interest in experimental fluid mechanics.
- Experience with experimental (fluid) mechanics or in designing laboratory experiments.
- Excellent written and oral communication skills in English. (French is not required)
- We offer
- Opportunity to perform state-of-the-art research in one of the most dynamic scientific institutions in Europe.
- Competitive salary and excellent educational conditions.
- Term of employment: 1-year fixed-term contract (CDD), renewable for 4 years.
- Informations
- CV
- Motivation statement (please indicate your earliest availability date)
- Grades from bachelor and master studies
- Working place : Lausanne
- Contract Type : CDD for 1 year, renewable for 4 years
