Hole-Pattern Seals Performance Optimization Using Computational Fluid Dynamics and Design of Experiment Techniques

A main goal of non-contacting mechanical seals is to provide minimal leakage during operation. This may be achieved by specifying a small clearance between the mating faces that is just enough to avoid rubbing contact while allowing some tolerable leakage. The amount of leakage flow is reduced through the acceleration and deceleration of the fluid through a tortuous path, so the sealing performanc…
