Sparse Days Meeting 2013

Sparse Days Meeting 2013 at CERFACS, Toulouse
June 17th-18th, 2013

 

The annual “Sparse Days at CERFACS” will take place on the 17th and 18th of June, just before the Preconditioning 2013 meeting at Oxford.
We intend to finish formal proceedings on the Tuesday in time to allow participants to catch the evening flight from Toulouse to London Heathrow.
The Sparse Days meeting will be similar in format to previous years.
No invited speakers and all talks in plenary session. As it is before the preconditioning meeting, we might expect an emphasis on associated areas, but contributions on any aspects of sparsity are welcome. In particular, talks on sparse optimization and on data assimilation would fit well with some of the current research at CERFACS.


Registration (Deadline : April 30th)

There is no registration fee and a limited amount of very low cost accommodation is available on site at the Meteo residences.

Registration and requests for accommodation should be sent to Brigitte Yzel (brigitte.yzel@cerfacs.fr).
The deadline for doing this is 30 April 2013. However, it will help greatly with our planning if you can let us know in advance of that deadline that you plan to come.

Titles and abstracts for presentations of 30 minutes (although you can offer a shorter talk if you wish) should be sent to Xavier Vasseur (vasseur@cerfacs.fr). The deadline is the same (30 April) but these can be sent later than the registration.

First 360-degrees Large-Eddy Simulation of a full engine

Jérôme DOMBARD |  17 June 2020

Within the PRACE project FULLEST (First fUlL engine computation with Large Eddy SimulaTion), a joint collaboration between CERFACS, SAFRAN and AKIRA technologies, Dr. C. Pérez Arroyo (post doctoral fellow at CERFACS) has carried out under the supervision of Dr. J. Dombard the first high-fidelity simulation of a part of the real engine DGEN380 (for now, from the fan to the combustion chamber). This 360-degrees integrated large-eddy simulation contains around two billion cells on the three instances, carried out with the AVBP code of CERFACS.  The CPU cost is obviously large but still within reach, performing around one turn of fan during 5 days over 14400 skylake cores. Post-treatments are in progress and already show, among other complex phenomena, a strong interaction between the high pressure compressor and the combustion chamber (see forthcoming paper GT2020-16288 C. Pérez Arroyo et al). Below a video showing: in the fan an isosurface at mid-height of the vein colored by the Mach number, in the high pressure compressor a gradient of density, in the bypass of the combustion chamber the static pressure and in the flame tube a temperature field. One of the goals of the project is to create a high-fidelity unsteady database to study interactions between modules and may help other teams to develop new lower order models and/or validate existing ones. Beyond the feasibility and the maturity of the AVBP code, this kind of calculation is an important milestone for the aeronautical industry and would allow to apprehend earlier in the design the effect of integration and installation and thus, to reduce the cycle and therefore the cost of the future aircraft engines. PRACE and GENCI CPU ressources and Safran Tech/DGAC fundings are gratefully acknowledged, along with the invaluable technical support at CERFACS: Dr. G. Staffelbach, Dr. F. Duchaine, Dr. L. Gicquel, Dr....Read more
