EFFECT OF SURFACE CURVATURE ON LAMINAR FILM CONDENSATION.

Author(s) : TAGHAVI K.

Type of article: Article

Summary

TRADITIONALLY THE MOMENTUM EQUATION WRITTEN IN CARTESIAN CO-ORDINATES HAS BEEN USED IN THE STUDY OF LAMINAR FILM CONDENSATION, PROVIDING THE FILM THICKNESS IS MUCH LESS THAN THE RADIUS OF THE CURVED SURFACE ON WHICH THE CONDENSATION OCCURS. THE AUTHOR HAS CONDUCTED A STUDY TO QUANTIFY THE ACTUAL EFFECTS OF SURFACE CURVATURE WHEN CONDENSATION OCCURS ON A HORIZONTAL TUBE. THE RESULTS ARE SHOWN AS A NUMERICAL VERIFICATION IN WHICH THE ORDER OF VARIATION OF THE NUSSELT NUMBER IS DEMONSTRATED. HOWEVER, IN THE ORDINARY RANGE OF NUSSELT NUMBERS, THE CURVATURE EFFECT IS NEGLIGEABLE, GIVING AN ERROR OF LESS THAN 1.0%. D.W.H.
