Design and manufacturing of modular self

When hydrostatic journal bearing is rotated hydrodynamic effects are introduced. Often, these effects are ignored by assuming them to be insignificant. Two non-dimensional parameters were derived to estimate the significance of the hydrodynamic effects and limits to these parameters were searched numerically.
