摘　　要：针对一种带入口旋流器的新型文丘利调风器出口流场进行了数值模拟 ,数值模拟结果与常规文丘利调风器出口流场数值模拟结果进行了对比分析 。The aerodynamic field for Venturi oil burner with an intake swirler is simulated by numerical analysis method . Through comparing results of numerical simulation and experiment, the physical model and process method developed by this paper are shown satisfactory. On the basis, the external aerodynamic field characteristics with different design parameters under cold condition for some marine boiler's Venturi oil burner are predicted and compared with normal Venturi oil burner.
