研究了空气分别在有无混合器的圆形直管内湍流流动时的传热膜系数α,比较了两种情况下α及准数关联式的差异。结果表明：在相同条件下,空气在有混合器的强化传热管中其α远高于无混合器的圆形直管;且空气在强化管内湍流时的α其准数关联式不同于圆形直管。
研究瞭空氣分彆在有無混閤器的圓形直管內湍流流動時的傳熱膜繫數α,比較瞭兩種情況下α及準數關聯式的差異。結果錶明：在相同條件下,空氣在有混閤器的彊化傳熱管中其α遠高于無混閤器的圓形直管;且空氣在彊化管內湍流時的α其準數關聯式不同于圓形直管。

Film heat transfer coefficient α of air and its associative parameter in intensified and straight tube were studied.The difference of two cases was also compared.The result showed that in the same condition,the coefficient α in intensified tube distinctly exceeded the straight tube and the associative parameter of intensified tube differed straight tube.
