摘要
分析了喷管摆动对发动机内流场的影响,针对喷管摆动情况下的流场特点,采用动网格技术及用户自定义(UDF)编程,实现与喷管摆动相对应计算区域的实时变化,并对具有摆动喷管的发动机三维内流场进行了数值模拟,得到了发动机内流场的详细情况。
According to the characters of the flow field in the case of nozzle swaying, dynamic mesh and UDF programming technology are used to realize the real-time changing of the calculating area corresponding to nozzle swaying. This paper simulates the 3-D internal flow field for the motor with swing nozzle, obtains the detailed distribution about the internal flow field for the motor and analyses the effect on the motor＇s internal flow field when the nozzle sways.
