采用贴体坐标系和ＳＩＭＰＬＥ法，对固体发动机在旋转热试车条件下的燃烧室内流场进行了数值模拟。不同燃烧时刻的计算结果表明： 旋转对固体发动机燃烧室燃气流动结构的影响随着燃烧肉厚的退移而显著增强； 在发动机药柱的前翼燃烧消失后， 前封头开口区域的切向涡开始变得强烈； 切向涡的分布呈现Ｒａｎｋｉｎｅ 涡的特点， 在发动机前开口区域涡的固核半径极小， 旋转速度极大， 这将严重影响该区域的热防护， 应引起有关设计人员的高度重视。
By using the body coordinate system and the SIMPLE method, the numerical simulation of the flow field in a combustion chamber under the condition of a rotating heat test is carried out. The calculation results of different combustion moments show that the influence of rotation on the gas flow structure of the combustion chamber of the solid engine is significantly enhanced with the flesh retreat; after the combustion of the front wing of the engine cylinder disappears, the tangential direction Vortex began to become strong; the distribution of tangential vortex Rankine vortex presents the characteristics of the front opening area of the vortex core solid radius is extremely small, the rotation speed is extremely large, which will seriously affect the area of thermal protection should be caused by the designer The height of attention.
