ERCOFTAC Workshop Series
Direct and Large Eddy Simulation (DLES)
The DLES series was launched by the ERCOFTAC Special Interest Group 'Large Eddy Simulation' in 1994 to serve as a platform for the exchange of state-of-the-art simulation techniques aimed at partially or fully resolving instantaneous turbulent flow structures. With the continuous growth of computational capabilities, these methods have gained increasing importance in both research and industrial contexts. Since its inception, DLES conferences have been held approximately every two years to address emerging developments and new challenges.
"It is a truism that turbulence is an unsolved problem, whether in scientific, engineering or geophysical terms. It is strange that this remains largely the case even though we now know how to solve directly, with the help of sufficiently large and powerful computers, accurate approximations to the equations that govern turbulent flows. The problem lies not with our numerical approximations but with the size of the computational task and the complexity of the solutions we generate, which match the complexity of real turbulence precisely in so far as the computations mimic the real flows. The fact that we can now solve some turbulence in this limited sense is nevertheless an enormous step towards the goal of full understanding." [P.R. Voke, L. Kleiser & J.-P. Chollet, Proceedings of DLES 1, 1994]
