| Abstract: | The transfer region of jet flow characterizes the energy conversion performance and flow feature of free surface jet. The flow structure of transfer region of free surface jet has not been revealed thoroughly so far. This paper presents a numerical model for axisymmetry and none-swirl viscous jet with needle-nozzle mechanism. The flow structure of transfer region and its exhibition have been investigated through numerical analysis. Of the numerical results, the relation between energy conversion and flow characteristics of transfer region has also been discussed in detail. |
