An integral procedure for a two-phase boundary layer in laminar film condensation. (English) Zbl 0594.76096
Summary: A general integral procedure has been developed for the analysis of laminar film condensation heat transfer. A solution of the gravity force condensation problem with constant properties is presented, including the effect of the drag due to an initially stationary body of pure saturated vapor. The present integral method, based on the two-phase boundary layer theory, assumes a finite density-viscosity ratio between the liquid and vapor phases, and can, in fact, be employed under almost all possible two dimensional and axisymmetric geometrical configurations. An extensive comparison of the calculation results with available exact solutions reveals an excellent performance of the present integral procedure.
