The aim of this project is to perform numerical simulations of droplets evaporation in turbulent flows. Many industrial and natural processes, including spray evaporation and combustion in engines, rain and respiratory droplets. We will in particular target liquid/air mixtures. The main objective is to generate models that can accurately predicts the droplet size distribution during the evaporation process.
Project description
The Department of Mechanics and Maritime Sciences is offering a doctoral position to investigate, quantify, and model the impact of turbulence on the dynamics of evaporating droplets. We will combine different numerical techniques including Direct (DNS) with interface resolved droplets and Eulerian-Lagrangian approach and Large-Eddy (LES) Simulations, together with stochastic models to predict the droplet number and size distribution in turbulence. The research project requires unique numerical expertise. The successful candidate will have access to state-of-the-art numerical codes running on different large-scale computers. The successful candidate will be joining an internationally active research group in fluid mechanics with experienced post-doctoral researchers as well as PhD students. Several joint publications in internationally leading scientific journals and attendance at international conferences is expected.
Information about the division and the department
The position will be open at the Fluid Dynamic division.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.
