带入口旋流器的文丘利调风器的内外部等温流场的数值模拟

针对带入口旋流器的新型文丘利调风器流场的数值模拟，提出了一种分析模型和处理方法。通过模拟结果与试验数据的对比分析，表明本文作者建立的模型及处理方法是成功的，据此进一步对某船用锅炉带入口旋流器的新型文丘利调风器的内外部等温流场进行了预测分析。

Numerical Simulation of the Inner and External Isothermal Flow Fields of a Venturi Air-register Containing an Inlet Swirler

With respect to the numerical simulation of the flow field of a novel Venturi air register incorporating an inlet swirler proposed is an analytical model along with a processing method. A contrast analysis of the simulation results and test data indicates that the proposed model and processing method is quite effective. On this basis a prediction analysis is conducted of the inner and external isothermal flow fields of the above mentioned Venturi air register for a marine boiler.
