Effect of lubricant inertia in externally pressurized conical bearings with temporal dependent viscosity (Q1912991)

The influence of convective inertia on the characteristics of a parallel gap conical bearing which rotates with a uniform angular velocity is investigated. The lubricant is assumed to be incompressible, and the viscosity varies exponentially with temperature. Inertia terms in the governing equations have been averaged across the film-thickness and the resultant system of equations is solved numerically to determine various bearing characteristics. It has been observed that the inclusion of inertia terms causes a decrease in the dimensionless load capacity for a lubricant whose viscosity is weakly dependent on temperature, irrespective of the temperature setting of the slider.
