Postdoc in Lagrangian modelling of droplets and crystals in turbulent clod
Climate change is a socio-economic challenge, and climate simulations are the only scientific tool to predict our planet's future climate. Clouds are crucial for weather and climate predictions, rain formation, and the water cycle. According to the Inter-governmental Panel on Climate Change (IPCC), cloud modelling is one of the least understood domains in climate sciences and is “listed as one of the most urgent problems requiring scientific attention”. Clouds are considered the largest source of uncertainty in climate predictions because it is complicated to accurately model the small-scale process (microphysics) inside clouds occurring in a range from meters to nanometers in a global climate model where the resolution is of the order of Kilometers.
Project description
The Department of Mechanics and Maritime Science at Chalmers University is currently offering a postdoctoral position focused on the dynamics of supercooled liquid droplets and ice crystals in turbulent clouds. The research methodology for this position involves utilizing Eulerian-Lagrangian Direct Numerical Simulations (DNS) coupled with phase change with the objective of generating new sub-grid models for Large-Eddy Simulations (LES) of turbulent clouds.
The project is funded by the European Research Council (ERC) under the MIXCLOUDS project, with the following objectives:
• Advance our knowledge on the interactions between different cloud particles in a turbulent environment
Improve the current models for tracking the position and effective sizes of ice and water droplets.
• This interdisciplinary project encourages collaboration with experts in statistics and atmospheric physics. The successful candidate will contribute to advancing our understanding of mixed phase clouds in the atmosphere.
Information about the division and the department
The position will be open at the Fluid Dynamic division of Mechanical and Maritime Science department. The research at the Division covers turbulent flow (both compressible and incompressible), multiphase flows, aero-acoustics and turbomachines. Our tools include both computations and experiments. The research covers a wide range of topics. In some research projects the smallest turbulent scales are studied whereas in others the function of a complete gas turbine is analyzed and modelled. The Division of Fluid Dynamics is part of Chalmers Sustainable Transport Initiative, Chalmers eScience Initiative and Chalmers Energy Initiative.
Major responsibilities
As a postdoc, you will be central to the development of the project, and also responsible for the implementation, validation and data analysis of the numerical tools.
You are expected to learn to develop your own scientific concepts and communicate the results of your research verbally and in writing. Your research activities will contribute to enhanced knowledge in the scientific field, in particular by presenting your results in scientific journals and at international conferences.
Qualifications
PhD in Mechanical Eng., Naval/Maritime Eng., Meteorology, Atmospheric Physics, Chemical Eng., Physics, Mathematics, Aeronautics or any relevant PhD program.
Contract terms
The position is a full-time temporary employment limited to a maximum of 2 years (+1 year of extension depending of performances and funding availability).
We offer
Chalmers offers a cultivating and inspiring working environment in the coastal city of Gothenburg.
