N2 - In order to research the flow mechanism in the supersonic jet element and optimize the performance of the supersonic jet element, the details of the flow field is numerically calculated with the Reynolds averaged NS equation and the k-ϵ turbulence model. The Mach number and static pressure distribution in the lower output channel are shown by cloud diagrams. The results show that the jet flow undergoes three different stages in the lower output channel, including expansion, compression and re-expansion; the compression process on the concave wall two forms: weak compression waves and shock waves; the degrees of the expansion varies with the inlet pressure; the intensity and position of the detached shock wave in the output channel have great influence on the thrust of the fluidic element.
