CNRS 
Development of a joint meshless / Eulerian approach to model spray atomization.
University of Rouen, Rouen
CORIA UMR CNRS 6614

Full Description:

The objective of the PhD is to couple a meshless method (Smoothed Particle Hydrodynamics - SPH ) and a usual Eulerian description. The SPH-Euler hybrid method will capture the physical properties of the spray near the injection area without mesh limitation and then, switch to a conventional Eulerian method (finite volumes description) - further into the chamber. This innovative approach in the area of ​​the injection will greatly reduce the computational cost that prevents high fidelity simulation in the field of liquid fuel atomization. This work involves a close collaboration with a post-doctoral fellow that will work specifically on the SPH methods optimization. The OpenFoam library for CFD will be used and the candidate will develop a specific solver.
The flow in and out of the injector will be modeled by SPH, freeing the simulation of the stress of the fine and costly mesh. The coupling of SPH with the finite volumes Eulerian description will be developed to integrate the atomization model ELSA (Eulerian / Lagrangian dispersed phase coupling). This work will also open the door to many other configurations in the field of hydrodynamics.

Note : According to the candidate availaibility, the PhD may begin during the spring 2015.
