Samenvatting (EN)

Aim: To study the similarity between the development of truncated inviscid turbulence and the FPU-problem. A study was made of the possible similarity between the development of truncated, inviscid turbulence and the FPU-problem. For the case of a constant time scale, which resembles the FPU-problem, a significant increase in the time to achieve equipartition was found when the initial energy was decreased. At first a few modes were generated and only rather late in the spectral development other modes appear and equipartition was established.
