Abstract
Static performance characteristics were comprehensively investigated for adiabatic finite-width turbulent journal bearings. A numerical method developed using the Legendre collocation technique was used to simulate liquid lubricant flows in various geometric conditions over a wide range of the mean Reynolds number. Both isoviscous and thermohydrodynamics (THD) were investigated. The least-squares method was applied to groups of parameters, yielding formulas for load capacity, friction coefficient, attitude angle, and side leakage. With the formulas derived in this study, designers can quickly determine static parameters of turbulent full journal bearings without the burden of labor-intensive numerical computation for the governing differential equations.
