Abstract

The study examines the combined impact of wall slip and pseudoplastic fluid on bearing system stability using a non-linear transient technique. The pseudoplastic effect is fused using the power law model, and the influence of slip lengths on lubricating surfaces is examined using the Navier slip condition. MATLAB code is utilized to solve the Reynolds equation using the finite-difference method and the Gauss-Seidel iterative method. By utilizing non-linear transient analysis, the journal center trajectories, which play a crucial role in determining the stability of the system, are estimated. The results of the investigation show that there is an approximate 21% improvement in the three-lobe bearing stability.
