特征线法在塞式喷管中的应用
Application of Characteristics Method to Aerospike Nozzle
【摘要】 介绍了特征线在塞式喷管中的应用 ,对于一些塞式喷管的特殊情况处理进行了详细的介绍 ,包括边界条件的处理、膨胀波和斜激波的处理等 ,并给出了典型的塞式喷管流场 ,给出了塞式喷管推力的计算方法 ,并把计算结果和实验结果进行了比较
【Abstract】 The Method of Characteristics (MOC) was applied to the aerospike nozzle.Some particular cases of the aerospike nozzle boundary conditions,expansive wave,oblique shock wave,and so on were considered.Typical flow fields of the aerospike nozzle were obtained.A method of thrust calculation was proposed.The results computed were compared with the experimental data.It is shown that the method is reliable and effective.
