Seals or gaskets that are compressed between walls of a container are important to many industrial applications. Understanding the performance of such seals requires an understanding of the microscopic geometry of the sealing surfaces, because the fluid seeps around the undulations of such surfaces. This paper presents strong computational evidence that the microgeometry of such surfaces depends on the difference between the mechanical pressure applied to the seal and the pressure of the leaking fluid. This work has the potential of simplifying and improving the theory and practice of sealing design and analysis.
