Abstract
Various methods and systems are provided for cryogenic heat transfer by nanoporous surfaces. In one embodiment, among others, a system includes a cryogenic fluid in a flow path of the system; and a system component in the flow path that includes a nanoporous surface layer in contact with the cryogenic fluid. In another embodiment, a method includes providing a cryogenic fluid; and initiating chilldown of a cryogenic system by directing the cryogenic fluid across a nanoporous surface layer disposed on a surface of a system component.
Claims20
A cryogenic system, comprising:
- a cryogenic fluid in a flow path of the cryogenic system;
- and
- a system component in the flow path, the system component comprising a nanoporous surface layer having a first side disposed on a surface of the system component and a second side opposite the first side, the second side of the nanoporous surface layer in contact with the cryogenic fluid flowing through the flow path.
A method, comprising:
- providing a cryogenic fluid;
- and
- initiating chilldown of a system component of a cryogenic system, the system component comprising a nanoporous surface layer having a first side disposed on a surface of the system component and a second side opposite the first side, the chilldown initiated by directing the cryogenic fluid across and in contact with the second side of the nanoporous surface layer.
