摘要：
By using the gradient method for heat transfer investigation, local heat transfer coefficients are determined for laminar film vapor condensation inside a horizontal tube. A study is made of the effect of vapor velocity, condensate inflow, and transverse mass flux on the intensity of the process. The occurrence of a pronounced asymmetry in the local heat transfer coefficients around the tube perimeter is noted, the decrease of which is promoted by an increase in vapor velocity and local heat flux.
