PhD-Position, ‘Numerical flow Simulation of Atmospheric Nocturnal Wind Bursts’, Netherlands

The Department of Applied Physics at Eindhoven University of Technology has 15 professorial chairs with about 65 academic and 60 technical specialists, as well as 110 graduate and 375 undergraduate students. The leading research themes cover functional materials, transport physics, and plasma physics and radiation technology. The department has extensive national and international partnerships, including industrial partners. It participates in several national (top) research schools, and in two national top technology institutes: Dutch Polymer Institute (DPI) and Materials Innovation Institute (M2i). Eindhoven University of Technology is one of the three participants in the Dutch 3TU Federation of Universities of Technology.

The project aims to solve a long-standing problem in boundary layer meteorology: to find the physical mechanism that drives intermittent (discontinuous) turbulence in the atmospheric nocturnal boundary layer. During intermittency, periods with ‘laminar’ flow are interrupted by chaotic bursts of turbulence and a significant transport of heat, moisture and momentum occurs. Bursts also act as an efficient ‘venting’-mechanism of pollutants that usually accumulate in quiet periods. The problem is highly relevant in weather and climate prediction and for air pollution problems. Current nocturnal boundary layer parameterizations are highly empirical and lead to significant errors in weather and climate predictions, especially in arctic regions.

The candidate will perform numerical simulations of stably stratified channel flows (with a Direct Numerical Simulation model). Different numerical experiments will be set up. The aim is to start with simplified studies and then increase the complexity of the simulations as to mimic atmospheric flows. Thus we start from non-interactive surface boundary conditions towards simulations that mimic (rudimentary) atmosphere-vegetation interactions. The outcome of the simulations will be used to develop a theoretical framework to predict this intermittence character of turbulence (using hydrodynamic stability analysis). Finally, results will be compared with readily available observations that were obtained in the outside atmospheric nocturnal boundary layer.

Requirements recent or impending MSc-degree in Physics, Mathematics, Meteorology or Mechanical Engineering with a special focus on fluid mechanical topics. Experience with numerical flow simulation (LES, or DNS) is a clear advantage. Finally, the candidate should have some interest in geophysical flows and be willing to follow courses on this topic if necessary.

Postdoctoral Position in Advanced Modelling of Gas-turbine Combustion, Netherlands

The Department of Mechanical Engineering considers as the core of their activities design, realization and analysis of new products, processes and materials. Besides the basis of (solid and fluid) mechanics, materials, control and thermodynamics, parts of mathematics, physics, chemistry and computing science are important supporting tools. The field is explored by a combination of modeling using fundamental concepts and applied engineering and technology. Automotive Engineering Science and Micro- amp; Nano-Scale Engineering are important departemental themes. The Mechanical Engineering Department comprises about 1000 students and 250 staff members. In the Combustion Technology Group, research is conducted on combustion processes in domestic and industrial applications. The main purpose of the research is related to the optimization of combustion processes and applications and the reduction of the pollutant emissions of, for instance soot, NO, CO, CO2 and partially unburned hydrocarbons. This is achieved by the development of new modelling and measurement techniques for flames and reacting flows, which is crucial for stimulating further technical developments in several areas in Combustion Technology, such as combustion in domestic and industrial installations, process equipment, biomass systems, gas turbines, internal combustion engines, etc. Tasks In the present project several complicated turbulent combustion phenomena are addressed on the level of modelling issues for future design CFD. The project partners are Siemens Power Group and Rolls-Royce and both aero and stationary combustion is considered. For these companies two Ph.D. students will develop new implementations to handle complex phenomena associated with preferential diffusion, complex combustion modes, quenching etc.. The postdoc will guide these developments and takes care of the theoretical framework within the method of Flamelet Generated Manifolds (FGM or FPI) and associated consistency issues. Requirements We are seeking an enthusiastic candidate who has been graduated from a PhD program (dr.) in turbulent combustion modelling. The candidate should be familiar with the framework of FGM). We are aiming for the best candidates that have strong affinity for theory, (consistent) implementation and at the same time candidates that never lose the focus towards the application of gas-turbine design. The preferred scientist will show a strong personal and scientific growth during the years. Excellent analytical and communication skills, and fluency in written and spoken English are essential. The postdoc should not reject the possibility to stay in the US for 1 year. Appointment and salary We offer: * A challenging job at a dynamic and ambitious University * The appointment is for two years. After a good evaluation your contract can be extended with another year. * The appointment is for two years with an intermediate evaluation after the first year. * The gross monthly salary will be in accordance with the Collective Labor Agreement of the Dutch Universities (CAO NU) and amounts initially to at least € 2861 per month (scale 10.4) depending on prior experience. * An attractive package of fringe benefits (including excellent work facilities, end of the year allowance and sport facilities). Application Deadline 01-09-2010.
