Abstract

A simulation analysis of structural strength and flow field for a disposable nozzle was carried out, which revealed stress distribution and character of flow field of the nozzle, and the results proved that the overall structure of the nozzle could meet the structural requirements. The working effect of annular cutter on the nozzle was simulated, and the results of numerical simulation and previous cutting tests were analyzed, suggesting necessity of a stair with certain thickness. The analysis results can provide references for structural optimization design of disposable nozzle.

Key words： disposable nozzle; annular cutter; numerical simulation; optimization
