摘要：
On the basis of the anaysis of wrical simulation methods for the complicated domain between tube bundles, an im-proved Lagragian discrete vortex method (DVM) and corresponding algorithm are put forward to solve the practical difficulties of flowacross tube bundles. With this method the amount of vortices can be reduced considerably, which makes quick calculation possible. Ap-plied to the practical configuration of horizontal tube bundles, the DVM simulation is carried out and compared with the experimental re-sults. Both the transient flow field and the profile of mean velocity and fluctuations are in good agreement with experimental results, whichindicate that the DVM is suitable for the simulation of single-phase flow across tube bundles.
