摘要
流场、热、结构问题 ,在传统的计算中 ,通常是先算流场、再算热响应和热结构问题 ,这显然是人为地分割了本身统一的、连续的过程 ,使得计算结果存在较多不足。本文给出一种把流场、热、结构耦合起来进行一体化数值模拟的方法。算例证明 。
Traditionally, the prediction of thermally induced deformations and stresses had been accomplished as a sequence of analyses: predicting heating rates on aerodynamic surface, determining structural temperatures and calculating structural deformations and stresses. Obviously, these approaches do not obey the objective, unitive and continuous physical processes. An integrated flow, thermal and structural numerical analog approach is presented in this paper. Computational results show that this method dynamically simulated the objective physical processes.
