The cell size also called core size refers to the distance between the opposite sides of the hexagonal honey-comb of the honeycomb seals is respectively 3.2 mm, 1.6 mm; and 0.8 mm.
Sealing Without Gas Swirl
Honeycomb seals are machined with individual chambers that create the pressure drop needed to slow leakage. Those chambers also disrupt circumferential flow around the shaft, preventing destabilizing forces caused by the gas swirl that is common with labyrinth seals.
From Aerospace to the Industrial Market
Honeycomb seals were initially used in the aerospace industry in air-breathing gas turbine engines as abradable stator components for high-pressure turbine stages. Later, they were used in cryogenic rocket engine turbopumps as a damper seal at the balance piston location.
Eventually the technology was adopted by the industrial market, which primarily focused on applications in high-pressure centrifugal compressors.
Advantages
Very low cross coupling
Higher direct damping that labyrinth seals
More forgiving than labyrinth seals in the event of a rotor-stator rub
Variety of materials available to serve a wide range of applications
Capable of sustaining higher temperatures than conventional labyrinth seals
