The sealing system for separating air and water is essential to increase efficiency when recovering hydropower energy, e.g., ocean current, tidal power, and streamflow energy. A newly invented biomimetic sealing system that artificially reproduces the mechanism of natural synovial joints is composed of two hydrated seal lips made of polyvinyl formal and a non-Newtonian fluid. In this report, an ideal...
A biomimetic bearing seal system has been developed to reduce frictional loss and improve the separation of air and water. The seal mimics the material properties and mechanical characteristics of articular cartilage found in natural synovial joints. It is made of the hydrated material polyvinyl formal (PVF), which has a porous structure, high wear resistance, and exhibits low frictional resistance...
