| 摘 要： | 为减少包含刚性运动的流固耦合问题动网格生成的计算量,以温度体模型动网格方法为基础发展了基准温度分布动网格生成方法.在介绍温度体模型方法的基础上,对基准温度分布动网格生成方法的基本原理和方法特点作出具体阐述.以NACA66翼型为例,将该方法应用于大角度旋转运动及平移和旋转同时发生的复合运动中.结果表明,该方法能极大减少计算量,所生成网格具有优异的变形能力,在翼型运动范围和旋转角度均很大的情况下,仍能保证网格的高质量.

| Abstract: | Reference temperature distribution method (RTDM) is a new dynamic grids method, which is applicable to the fluid-solid coupling problem including rigid motion with less calculation amount. The development of RTDM is on the base of temperature analogy method (TAM). This research introduces TAM firstly and then illustrates RTDM and its characteristics in detail. Finally, RTDM is applied to the dynamic grids generation of NACA66 airfoil with two kinds of motion. One is large angle rotating motion and the other is complex motion including both translation and rotation. The results verify that RTDM could decrease calculation amount to a large extent and the dynamic grids generated by RTDM are of high quality, even though at the case of both wide range of motion and rotating angle. |
