Clouds are crucial for weather and climate predictions. According to the 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. This project will address this challenge by using novel multiscale techniques developed for general multiphase flows that allow us to accurately solve the small-scale cloud turbulence and its impact on nucleation, evaporation and collisions of cloud droplets.
Project description
The Department of Mechanics and Maritime Science at Chalmers University is offering a doctoral position to investigate, quantify, and model the impact of turbulence on the dynamics of water droplets/aerosols inside warm ice-free clouds. The methodology combines different numerical techniques including Direct (DNS) and Large-Eddy (LES) Simulations, together with stochastic models to predict the water droplet number and size spectra inside clouds and the mechanics of rain formation. The aim is to measure the main microphysical processes that determine, in combination with turbulence, the cloud droplet sizes: nucleation of cloud condensation nuclei (CCN), growth by condensation of water vapor, growth by collisions/coalescence induced by turbulence and gravity. The project is highly interdisciplinary and involves interactions and collaborations with statistics and atmospheric physicists.
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 PhD student, you will be central to the development of the project, and also be 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.
The position also includes teaching courses within Chalmers' undergraduate level corresponding to up to 20 percent of the working hours
Qualifications
To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in a relevant field. You also need a MSc in Mechanical Eng., Naval/Maritime Eng., Chemical Eng., Physics, Math. Eng., Aeronautics or any corresponding MSc. The position requires sound verbal and written communication skills in English. If Swedish is not your native language, Chalmers offers Swedish courses.
Contract terms
Full-time temporary employment. The position is limited to a maximum of 4,5 years.
