摘　　要：运用FLUENT软件对圆管、椭圆管及交变曲面波纹管管束中强制对流空气热力过程进行了模拟,模拟数据经过Tecplot.10处理后直观地表征了3种管型管束中空气的速度场、压力场及温度场。结果表明,交变曲面波纹管在提高流体湍动程度及强化传热温差方面优于其它两种管型。By means of the FLUENT software, a simulation of the thermodynamic process of forced convection air in the tube bundle of circle tube, the elliptical tube and the corrugated tube of alternating camber were presented. The data of simulation was processed by Tecplot. 10,which provides a direct illustration of the velocity,pressure and temperature fields of the flowing air in the tube bundles of the three casts. A result demonstrates the advantages of corrugated tubes of alternating camber over the other two types of tubes in increasing flow turbulence and enhancing temperature difference.
