| 摘 要： | 以任意设计的固体火箭发动机装药几何形状为对象,分析研究了燃面燃烧移动的基本规律,提出了一种三维复杂燃烧移动边界的示踪方法。它可以用于流场计算、发动机性能预示计算和侵蚀燃烧计算中,也可以发展成为一种燃面计算的新方法。文中以假想三维局部翼形装药为例进行了数值计算。

| Abstract: | Any type grain designed in solid propellant rocket motor (SPRM) is considered in the paper. Based on basic law of burning-surface change, a method is presented to trace 3-D complex burning and ablating Surface. The method can be used in the flow field computation, SPRM performance prediction and erosive-burning computation. And it may also be developed into a new method for calculating burning-surface. As an example,computation of assumed 3-D grain with locally airfoil section was performed. |
