An approach simulating interacting solid, liquid, and gas domains for dynamic seal applications
Proceedings in Applied Mathematics and Mechanics, Volume 24, Issue 2, August 2024.Abstract In seal applications a solid elastic body (the seal) ensures the separation of a liquid (e.g., hydraulic oil in one chamber) from a gas (e.g., air in another chamber). In the case of a dynamic seal, the rod is moving and transports a thin liquid film from the liquid chamber into the air chamber.
