Heat transfer and flow modes of phases in laminar film vapour condensation inside a horizontal tube

摘要: Abstract By using the gradient method for heat transfer investigation, local coefficients are determined laminar film vapour condensation inside a horizontal tube. A study is made of effect velocity, condensate inflow, and transverse mass flux on intensity process. The occurrence pronounced asymmetry in around tube perimeter noted, decrease which promoted by an increase velocity flux. flow modes phases case incomplete identified ; need to take into account thickness when constructing map noted. correlation suggested calculate mean-integral condensation.
