Heat dissipation and energy transfer performance of helium face seal with spiral grooves at cryogenic condition

Low-grade thermal energy utilization: Technologies and applications

“…Additionally, the Stirling cycle is considered as a type of highly compact waste heat recovery system. In this Special Issue, Yang et al [27] focused on the stability and energy consumption of the helium face seal in Stirling cycle engines. They developed a numerical model to investigate heat dissipation and energy transfer routes under cryogenic conditions.…”
