首发时间:2009-07-14
摘要:本文基于无网格法首次提出了一种处理动边界问题的方法——重叠点云法(Overset Clouds of Points Method,简称OCPM),并将此方法成功地应用于NACA0012翼型振动问题和超音速运动圆球绕流问题的数值模拟,计算结果与实验结果和其它网格方法模拟的结果非常吻合,证明了基于无网格法的动边界处理方法——重叠点云法在求解含运动物体的非定常流动问题中的准确性和实用性。

Overset Clouds of Points Method – A Method Disposing Moving Boundary Problems Based on Meshless Method
Abstract:In this paper, a new method, which is called Overset Clouds of Points Method (OCPM), was first proposed to dispose moving boundary problems based on meshless method. The method is successfully applied to numerically simulate the flow field around NACA0012 airfoil with pitching oscillations and the fluid flow around moving sphere at supersonic speed. The simulation result shows good agreement with the experiment result, as well as the other simulation results which were based on the other grid method. The proposed OCPM can process the unsteady flow problems with moving objects accurately and practicability.
