The particulars of the adaptation of the CONV-3D module for modeling turbulent flows in reactors in the LES approximation are presented. The results of modeling coolant flow in a round tube with Reynolds number 4·10 3 –5·10 5 in comparison with the Blasius formula are presented. It is shown that the adapted module gives numerical results that coincide with the analytical estimates and DNS calculations but on much coarser grids, so that the calculations can be speeded up several-fold.

调整 CONV-3D 单相模块在 Les 近似中模拟反应器中的湍流

介绍了采用 CONV-3D 模块对 LES 近似中反应堆中的湍流进行建模的细节。给出了雷诺数为 4·10 3 –5·10 5 的圆管中冷却剂流动建模结果与 Blasius 公式的比较。结果表明，适配模块给出的数值结果与分析估计和 DNS 计算一致，但在更粗糙的网格上，因此计算速度可以提高几倍。
