本文从不同于以往文献的角度对所谓的附加质量效应进行了研究。用速度项的静态凝聚对整体流固耦合问题进行了划分。在此过程之后，介绍了不可压缩流体流动的经典稳定投影法。该方法可获得新的流固耦合压力分离格式，即使在附加质量效应较强的生物力学应用中也具有良好的收敛特性。当证明同样的投影技术必须在交错的FSI方法中实现时，该过程显示了它的力量。版权所有(C)2009 John Wiley&Sons，Ltd.
In this paper, the so-called added-mass effect is investigated from a different point of view of previous publications. The monolithic fluid-structure problem is partitioned using a static condensation of the velocity terms. Following this procedure the classical stabilized projection method for incompressible fluid flows is introduced. The procedure allows obtaining it new pressure segregated scheme for fluid-structure interaction problems, which has good convergent characteristics even for biomechanical application, where the added-mass effect is strong. The procedure reveals its power when it is shown that the same projection technique must be implemented in staggered FSI methods. Copyright (C) 2009 John Wiley & Sons, Ltd.
