The performance characteristics of viscoseals are analyzed including the effects of convective inertia and the groove side wall. For the geometries studied, the present theory correlates the experimental data for the sealing and friction coefficient better than previous theories. The sealing coefficient is found to be dependent on the Reynolds number and groove width-to-depth aspect ratio. Leakage and critical Reynolds numbers are also discussed.
