Objective
Turbulent flow fields laden with small particles much heavier than the gas phase occur in a wide range of natural and industrial processes such as pollutant dispersion in atmosphere, fuel injection into engine, piping in chemical engineering... The interactions between the particle and the turbulent flow imply a lot of interdependent effects, many of which remain poorly understood. The development of good engineering models using is therefore challenging. A long-term research project is going on at Kramer Laboratory, on the improvement of Eulerian models using direct and large-eddy numerical simulations (DNS and LES) of simple flows. This one- year project will be inserted into this lager project. The major objectives of this project are: gain a better understanding of the mechanisms associated with particle-turbulence interactions in a two-phase channel flow, and provide subsidies on how to model these effects in the context of Eulerian simulations. The project will consist of three stages:
-Adaptation of the existing code, to perform energy balance and spectra
-Simulations with different particle-loading and analysis of the results.
- Implications for two-fluid models. Some attempts will be made to provide ideas on how to model two-way coupling effects in terms of interactions involving multiple turbulence-scales (say, large and small scales ).Training content is based on both two-phase flows physics and numerical simulations. My PhD studies have brought me to reflect on particles effects on turbulent flows. The research project proposed at Kramers Laboratory will allow me to make the most of my knowledge of two-phase flows physics and complete my scientific training on that point. Till now, my competence is essentially based on experiments, this work will offer me the opportunity to extend it toward numerical simulations. For a more personal point of view, I am convinced it is essential that I should have an experience in a foreign structure to enhance my French training. This research project results from recent co-operation between Kramers Laboratory and IMFT (Institute of Fluid Mechanical of Toulouse). It will promote scientific exchanges between the two laboratories.
