A numerical simulation of the three-dimensional steady flow field in the whole flow field, from the inlet of the collector to the outlet of the diffuser, a 2k70 axial-flow fan is performed.
针对2k70型轴流式通风机从集流器进口到扩散器出口的内部三维全流场做了定常的数值模拟。

After this flow pattern transformed into a flow pattern with thermal chocking at the combustion chamber exit and with a pseudo-shock wave developing in the inletdiffuser.
之后，在燃烧室出口出现热拥塞现象、在进气道扩压段产生伪激波流态。

The inlet flow angle and diviation angle were confirmed which was applied to low cascade experiment result of American NACA, and controlled diffuser factor and flow deflection angle in design.
