摘要：

We present a comparison of the performance of vortex and pseudospectral methods in two reference flows: a homogeneous turbulent flow at low Reynolds number and a vortex reconnection case at a moderate Reynolds number. The results should contribute to a better understanding of the accuracy of vortex methods in both resolved and underresolved simulations. (C) 2002 Elsevier Science (USA).
