The end show that coefficient of convective heat transfer at thermal boundary condition is higher than that at definite heat flux boundary condition. if according to dimensionless equation of heat convection, nu number of the latter almost is mutiplied 1. 47 times of the formal, but the coefficient of convective heat transfer in tube between this two condition is almost equal
研究結果表明:在實驗室中電加熱方式得到的管外對流換熱系數低於工程中傳熱條件下的管外對流換熱系數，若按傳熱準則式關系，後者的努謝爾特數約為前者的1 . 4倍;而管內的對流換熱系數在兩種邊界條件下的差別不大。
