开发了大涡模拟（LES）三维计算流体动力学（CFD）程序AVBP，以产生一个能够预测内燃机循环变动的CFD工具。在第一步中的任意拉格朗日欧拉（ALE）方法到AVBP的实施进行了描述，允许移动固体边界。然后描述了条件时间插值（CTI）网格管理技术的原理和实现，并讨论了LES模拟的一些具体适应性。最后，第一次验证，因此获得的LES IC发动机代码的预测结果进行比较，在方形活塞实验。
The development of the Large Eddy Simulation (LES) 3D CFD code AVBP to yield a CFD tool able to predict cyclic variability in Internal Combustion (IC) engines is reported. In a first step the implementation of an Arbitrary Lagrangian Eulerian (ALE) method into AVBP is described, allowing to move solid boundaries. Then the principles and implementation of the Conditioned Temporal Interpolation (CTI) mesh management technique is described, and some specific adaptations for LES simulations are discussed. Finally a first validation of the so obtained LES IC engine code is presented by comparing predictions with findings on the square piston experiment.
