The velocity field and temperature field in transversally corrugated tubes of different structure have been numerically simulated

according to the field synergetic principle

the terbulent heat transfer in three kinds of these transversally corrugated tubes has been analysed.Considering the difference of flow resistance is different type of said tubes

the heat transfer ability of said tube types has been comprehensively evaluated and compared

therefrom

the best tube type being obtained.Results of analysis show that the comprehensive heat transfer ability of the best tube type is up to about 1.3 times of that in commonly used transversally corrugated tubes under condition of inlet flow velocity being in a range of 0.5~3 m/s.
