Abstract：In order to evaluate the difference of two different types of industrial nozzles' outlet flow parameters,using Computational Fluid Dynamics numerical analysis method,two different types of industrial nozzles under various working conditions were simulated numerically.The calculation results show that compared with linear nozzle,the curve nozzle has obvious advantages of uniformity of outlet flow parameters under the same initial condition.Two kinds of nozzles under the different working conditions,average static temperature,average static pressure and average total pressure of outlet flow of curve nozzle compared to linear nozzle,the highest increases are 0.8％,2.25％,3.43％ respectively.Therefore,using curve nozzle which is designed according to the supersonic characteristic line theory as the common industrial nozzle can reduce the internal mechanical energy loss,optimize outlet flow field quality,wtich can improve the efficiency and accuracy of industrial process technology.
