France: Postdoctoral Fellow in Thermal Engineering 2007
Category: Scholarship fellowship 2007 / 2008
French: Postdoctoral Fellow in Thermal Engineering at Ecole des Mines de Nantes
Postdoctoral Fellow: Research and Development in fluid mechanics and thermal sciences: application to fire safety.
Reference: DSEE-2006-MP-1
Numerical simulation of air-curtain-based separation systems with application to fire safety in semi-confined areas.
The work proposed here comes within a broader research programme devoted to fire safety on board ships.
More specifically, it is aimed at investigating the potential benefits from using air-curtain-based systems as auxiliary fire safety systems to hamper smoke and heat propagation in case of fire in confined areas, facilitate people evacuation in a self-rescue phase and make easier rescue team access to the incident place. Appropriate designs can also reduce oxygen supply locally, and contribute to fire self-extinguishment.
Various air curtain arrangements will be investigated numerically with the LES code FDS (Fire Dynamics Simulator). Simple corridor-like geometries will be considered first for qualification and validation purposes. Numerical results (flow and scalar fields) will be compared with the results from earlier PIV and tracer gas laboratory experiments that have been conducted at the Ecole des Mines de Nantes (including the air curtain impingement region in which we experimentally detected and educed coherent structures whose populations have been subsequently characterized statistically). They will be compared also with numerical results obtained from simulations with statistical CFD codes.
Then, numerical tests will be performed to investigate the conditions that can arise locally during a fire on simple models of elements (cabin, corridor, for example) when an air-curtain-based fire safety system is operated, assess and quantify the efficiency of the tested ventilation arrangements, and suggest appropriate designs.
Benefits
12-months fixed term employment contract with health and social security coverage. Paid attendance of the fellow to international workshops and conferences. Cooperative work with academic and industrial partners. Financial support is available for another 12-month experimental research work on the same topic.
Additional Information
This post-doc project must be viewed as an exchange process whereby the candidate will bring his skills to contribute to the development of the proficiency of our laboratory (introduction of FDS) while acquiring or improving knowledge in the field covered by the present project.
Requirements
PhD in Engineering or Physics (A PhD is considered as a period of Research experience equal to at least 3 years). The candidate must have a solid background in turbulent fluid dynamics and heat transfers. The candidate should have a good sense of physics. Ideally, he should be familiar with plane air jets. Candidates with experience in running / developing the FDS code are especially welcome.
Good ability for written and oral communication in English is necessary (publications, conferences). Knowledge of French is not required.
Application
The candidate will be asked to commit himself for the 12 months of the project.
Financial support is available for another 12-month experimental research work on the same topic. The applications of candidates who are ready to embark on a 2-year post-doctoral project and take in charge both the numerical and experimental aspects of the problem will receive special attention.
Applications should include a CV, a motivation letter, a short description of previous research experience and the names of people from whom references can be obtained. Send or email to:
