Gas bearings have emerged as an alternative to conventional bearings lubricated by greases and oils due to the growing requirement for environmentally sustainable, high-speed as well as extreme temperature applications in turbomachinery, e.g. in hydrogen liquefaction processes [1-2]. Hydrogen is a source of green energy as it is clean, non-toxic, and has no greenhouse effect [3]. The present study deals with the performance analysis of hydrogen gas-lubricated hybrid journal bearings for hydrogen compressors. The behavior of different gases such as nitrogen, air, and helium on the bearing performance parameters has also been studied. The modified Reynolds equation was solved using the Finite Element Method (FEM) by incorporating suitable boundary conditions. The static and dynamic performance characteristics of gas-lubricated bearings have been numerically computed. The numerical simulated results show that bearing performance significantly depends on the types of gases. The hydrogen-lubricated gas bearing provides a lower value of frictional losses as compared to other gases-lubricated bearings. The present study is expected to be beneficial to the bearing designers. Furthermore, it is shown that surface micro-texturing can be used to enhance the tribological behavior of hydrogen-lubricated hybrid journal bearings.
