Two polymers and five metal pairs were tested at six low temperature points and three
constant load speeds. The tribological properties were determined by joint iterative coupling …

A check valve which is a critical component for cryogenic sorption compressor, has been
developed previously by several researches. Its leakage rate was phenomenologically …

A significant number of valves constitute a vital component of the containment pressure
boundary of a nuclear power plant, and their leakage rates under accident conditions must …

The small angular deflection of the spool under the action of non-equilibrium force is a main
reason for valve seal failure. In the present study, a prediction model of the valve seal …

Cryogenic propellant servicing of any advanced propulsion system before launch is very
critical due to complex two phase flow during chilling, transient heat transfer, pressure and …

Sealing performance under cryogenic temperatures should be a consideration in the
development of a cryogenic valve for use in cryogenic engineering. In the present work, a …

Cryogenic valves are mostly designed at the room temperatures and served at the cryogenic
temperatures. The wide temperature difference between design and service conditions …

Cryogenic propellant servicing in advanced propulsion systems requires careful time
management, as the austenitic steel safety relief valve, prone to seat leakage from repeated …

Some systems operate at low temperatures and high pressures, necessitating a high level of
system stability. As a result, each component of the system must undergo low-temperature …

Check valve is an important part of the range hood. In this paper, a novel structure of check
valve is presented to promote the opening performance. The numerical model of the …
