Examples
- This application covers the cases where the condensing side film coefficient does not change significantly over the temperature range
这个主要应用在冷凝端膜系数在超过温度范围时变化不明显。 - Analytical relationships are obtained for calculation of the coefficient of heat transfer for condensation in tube , the relative difference between the experimental value and the calculated value is smaller than + 15 %
关联出了相应的水平管内冷凝传热膜系数的计算式，计算值与实测值的偏差在15以内。 - The results indicate that the qualitative behavior in this process is similar to that observed in condensation of vapor at or above atmosphere pressure , the coefficient of heat transfer for condensation in tube , the coefficient of heat transfer in total increase with the increasing of heat flux density and vapor pressure . however , heat flux density and vapor pressure have a more significant effect on them
发现水平管内低压蒸汽冷凝过程与常压条件下蒸汽冷凝过程相同，管内冷凝传热膜系数、总传热系数随热流密度、蒸汽压力的增大而增大，但热流密度、蒸汽压力对低压蒸汽冷凝有着更为显著的影响，管外冷却水流量对其影响并不明显。 - The interactions between heat flux density , vapor pressure , vapor velocity and the coefficient of heat transfer for condensation in tube , the coefficient of heat transfer in total are investigated . the relationships between heat flux density and the total difference in temperature , the difference of temperature , pressure drop of vapor from the entrance of the tube to the exit are investigated as well
考察了冷却水流量、温度恒定条件下热流密度、蒸汽压力、蒸汽流速对冷凝传热膜系数及总传热系数的影响关系，同时考察了总传热温差、蒸汽进出口温差及压差随热流密度变化的关系。
