Cerfacs Enter the world of high performance ...


  30 November 2015

Cerfacs contributed to the writing of the book "CLIMATE CHANGE & SATELLITE" (2015). In this book, sixty internationally recognized scientists (including several IPCC contributors) provided an update on the state of knowledge in different areas related to global warming. The article on Cerfacs can be read at the following address:

The Paul Lafitte combustion prize team for Dr Michael Bauerheim

  25 November 2015

The french Section of the Combustion Institute has chosen Dr Michael Bauerheim for his 2015 PhD prize. Dr Bauerheim worked on combustion instabilities in gas turbines (collaboration with SNECMA). His PhD manuscript is available here: . The jury was impressed by the originality of the theoretical and numerical approaches as well as by the numerous publications produced by Dr Michael Bauerheim.

Living a PhD life at CERFACS : a new movie !

  27 October 2015

Everything you wanted to know about the life of PhD students at CERFACS is now available … here. This movie produced with the support of the European Marie Curie project COPA GT presents the everyday work of two PhD students involved in CFD research at CERFACS for industry.  

Inauguration of the new Cerfacs’ supercomputer

  1 October 2015

On 30 September  2015 , Cerfacs and its associates (Airbus Group, Cnes, EDF, Météo-France, Onera, Safran and Total) inaugurated the latest Cerfacs' supercomputer named Nemo. With a peak performance of 242 Tflop/s, this Lenovo configuration will allow Cerfacs' research teams to meet new and increasing scientific challenges. This inauguration was an opportunity to share, with the audience, the fields of application that the Cerfacs' computing resources allow to address in fields as varied as ten-year climate prediction, assessment of natural and industrial risks (flood forecasting, anthropic emissions impact), optimisation for oil exploitation, design time reduction for launchers and aircrafts (improvement of engines and turbines, noise prediction, reduction of pollutants) ...

SIMAC Project is one of the six success stories of the 2014th PRACE annual report

  16 July 2015

The project SIMAC (Simulation of Ignition Mechanisms in Annuar multi-injectors Combustors and comparison with experiments) carried out by CERFACS and EM2C was selected by PRACE among the 8 success stories in the 2014 annual report (). For the very first time, Large Eddy Simulation of the ignition of an annular combustion chamber has been validated in details by comparison with measurements of ignition in a transparent annular burner at EM2C (MICCA). Ignition being critical in the design of more efficient aeronautical burners, the results of this project will be used to improve the capacity of ignition and re-ignition of future burners.

2015 Numerical Simulation Trophy “collaboration” awarded to Cerfacs and Turbomeca

  30 June 2015

The « méthodes » group from TURBOMECA (led by L. Pons) and the CFD - combustion group from CERFACS (led by T. Poinsot) have recently actively collaborated to improve the design and life duration of helicopter engines. Indeed in light of the ever increasing environmental constraints and current needs for ever more performant engines, being able to accurately predict the temperature levels entering the turbine stage becomes a key design constraint. Not only are the hot gas issued by the combustion process in the combustor still increasing, but their temperature now well overshoots the melting temperature withstood by existing materials of such engines. In an effort to improve the quality of the predictions issued by existing tools on this issue, CERFACS’ team with the collaboration of the TURBOMECA team have supported multiple research projects (funded by RTRA, Europe…) to propose a CFD solution constructed around CERFACS’ code that is AVBP. From this active collaboration, recognized here by Teratec, has emerged a tool called TurboAVBP that can at once simulate the combustion chamber and the turbine stage thereby giving access to the entire spacial and temporal description of the flow field as well as its temperature level in the real engine geometry. Constructed from the most advanced CFD research solutions, this tool hence allows to significantly improve the prediction quality of the next generation of engines at the design stage and provides a significant advantage to SAFRAN group in comparaison to its concurrents.
