RANS and LES: our allies in the quest for turbulence

Dr Philippe Spalart
Boeing
November 19, 2018 - 18:30 to 20:45

Oxford e-Research Centre, 7 Keble Road, Oxford, OX1 3QG

  • Seminar
  • Registration required
  • Open to all

Dr Philippe Spalart - Senior Technical Fellow at Boeing has kindly agreed to give a talk on his transformative work on turbulence modelling. The creator of two of the most widely used turbulence models: the Spalart-Allmaras RANS model and Detached-Eddy Simulation (DES) are used globally to design the next generation of aircraft, road cars and to enable the study of fundamental flows. His talk entitled RANS and LES: our allies in the quest for turbulence will discuss the future of turbulence modelling and his work to date.

Wine, beer & snacks from 6.30pm and the talk will be begin at 7pm.

Speaker Info

Philippe Spalart studied Mathematics and Engineering in Paris, and obtained an Aerospace PhD at Stanford/NASA-Ames in 1982. Still at Ames, he conducted extensive Direct Numerical Simulations of transitional and turbulent boundary layers. Moving to Boeing in 1990, he created the Spalart-Allmaras one-equation Reynolds-Averaged Navier-Stokes turbulence model. He wrote a review (once described as “discerning and sobering”) and co-holds a patent on airplane trailing vortices. In 1997 he proposed the Detached-Eddy Simulation approach, blending RANS and Large-Eddy Simulation to address separated flows at high Reynolds numbers with a manageable cost. He was elected to the National Academy of Engineering in 2017. Recent work includes refinements to the SA model, computational aeroacoustics, and theories for aerodynamics and turbulence.
