THERMODYNAMIC AND MECHANICAL ANALYSIS OF PRESSURE DISTRIBUTION IN GAS-FLUID INTERFACE

摘要

Thermodynamic properties and pressure distribution in gas-fluid interface were investigated by using energy and mechanical analysis techniques. Based on the study of interfacial phenomenon, differential equation and cumulative distribution of pressure were derived. Comparing with the Gibbs's method, it shows that the pressure changes sharply in the interface when its thickness limits to zero, the deduction is accord with the Young-Laplace's equation.
