Abstract
The effect of inertia and flow development on bearing behavior has been investigated numerically and experimentally. The full Navier-Stokes equations are solved for a slider-type bearing and compared to experimental results. The computational domain covers the far upstream region as well as the bearing gap region to evaluate the inlet condition correctly. Experiments have been conducted with a simulated partial-arc bearing. The measured far upstream velocity profile is adopted as a boundary condition in numerical analysis instead of assuming a uniform bearing inlet velocity profile which has been used by previous authors. The resulting velocity profile across the inlet gap is neither uniform nor entirely viscous in nature. Numerical results agree well with experiment in a range of he modified Reynolds number 3 to 30. A significant so called “rum pressure” effect is found and this can be portrayed through a loss coefficient.
