| 摘 要： | 采用ＳＦＤ方法，在ＥＸＣＥＬ软件上利用ＮＮＤ格式数值模拟了激波与平板边界层之间的相互作用以及激波与管道壁面边界层的相互作用，即高超声速进气道隔离段内激波串流动现象。该方法的特点是简单、直观而且不用常规编程，计算结果基本反映了流场的基本结构，表明ＳＦＤ方法是一种具有潜力的计算方法。

| Abstract: | The interactions of shock waves with boundary layers on the flat plate and shock chains in the isolator of the hypersonic inlet were numerically simulated respectively by the method of Spreadsheet Fluid Dynamics (SFD) in the EXCEL software with NND algorithm The SFD method is simple and demands no ordinary program processing The numerical results reflected the general structure of the flow field which means that SFD may be a potent computational fluid dynamics method |
