多重网格方法在通风空调气流数值模拟中的应用

Multigrid Method Applied to the Air Numerical Simulationin Ventilating and Airconditioning

多重网格方法（ＭＧＭ）具有较快的收敛速度．本文讨论了全近似完全的多重网格方法（ＦＡＳ－ＦＭＧ）在三维室内气流数值模拟中的应用．通过对计算实例的结果分析，表明它的收敛速度比单层网格迭代法提高了３～４倍，并明显地改善了收敛过程的稳定性．

ultigrid Method (MGM) is of high convergence rate. This paper discusses the application of FASFMG to the numerical simulation of threedimensional indoor air. The comparisons of engineering example demonstrate that the convergence rate is accelerated by 3~4 times, compared to the single grid system, and also the convergence stability is apparently improved.
