Non-linear analysis reveals fluid inertia and texture geometry affect stability in rotating machinery.

Protrusion-textured bearings show up to 30% higher critical mass-parameters than plain bearings, indicating superior stability.
Increasing the dimple aspect ratio and area density enhances stability, but non-dimensional clearance negatively impacts it.
In a non-linear transient analysis, fluid inertia effects are significant at high speeds and low-viscosity lubricants.
Higher modified Reynolds numbers improve stability in lightly loaded bearings but may destabilize heavily loaded ones.

Das et al. (2025) studied this question.
