Abstract

The thesis presents a mathematical model for predicting surface tension in condensate films. The approach taken to this study is different from how surface tension is normally approached. Surface tension is primarily determined through laboratory measurements. This work shows how it can be determined mathematically based on the formulation of bonding energy between atoms as described by the Lennard-Jones potential.

The results are used to predict the surface tension of a selected group of elements and molecules. Predictions from the model compare favorably with the documented surface tension values of the selected elements. However, the model does deviate somewhat from the documented surface tension values for the larger molecules. This model should be useful in formulating the response of various nano and micro systems to capillary action.
