Turbulence effect on dynamic performance of non-circular floating ring bearing

The current work scrutinizes the impact of turbulence on the dynamic performance of the novel variation of hydrodynamic bearing, especially Non-Circular Floating Ring Bearing. A bearing comprises of a shaft, floating ring, and non-circular outer housing. The journal and floating ring are cylindrical, whilst the outer housing is noncircular. The noncircular designs of journal bearing provide better stiffness characteristics. The well-established Navier-Stokes and continuity equations (cylindrical coordinates) have been adequately utilized with the linear turbulence lubrication theory. Dynamic characteristics of modified floating ring bearing have been scrutinized at different numerical values of film eccentricity ratio (outer) and Reynolds numbers up to 9000. The current analytical work envisages satisfactorily well performance of modified floating ring bearing in the regime of turbulence.

Automated summary

The current study investigates the impact of turbulence on the dynamic performance of a novel non-circular floating ring bearing design, showing that the non-circular design provides better stiffness characteristics and the modified bearing performs well under turbulent conditions.
