An analysis of a self-energized hydrostatic shaft seal operating with incompressible fluid in the laminar regime is presented. Dimensionless results are optimized for maximum stiffness. Comparisons are made between full annulus and sectored annulus recess configurations. It is shown that translational and torsional stiffnesses are critically dependent upon orifice size. A sample problem is included to demonstrate use of equations, design curves and criteria developed.
