| 摘 要： | 采用FTCS有限差分格式方法,考虑场量具有轴对称的特点,利用二维三分量的初始条件,对在非静态极限下空间飞行器与周围等离子体在远尾区发生非稳态非线性相互作用的耦合方程进行数值计算,得到电势的时空演化图。结果显示,在飞行器远尾区形成了电双层结构。研究该结构对探测隐身飞

| Abstract: | A numerical simulation of non-steady non-linear interaction between moving bodies and plasma in the far wake region is presented.Considering the property of axial symmetry of field quantity,the initial conditions of two dimensions with three field components,the FTCS method,i.e.time forward difference and space central difference method,has been used.The space evolution of potential at different time has been obtained.The results of numerical calculations show that the structure of electric double layer is ... |
