This article investigates the static and dynamic performances of bionic textures fused micro-pocketed journal bearing considering cavitation. The new bionic textures placed inside the micro-pocket toward the trailing side has been conceived inspired from the skins of freshwater fish. The mass conservation satisfying partial differential lubrication equations for the static and dynamic pressures are discretized using the finite volume method (FVM) followed by simultaneous solution of the system equations using the Fischer–Burmeister–Newton–Schur (FBNS) and the Broyden’s method with Sherman–Morrison formula. The minimum film thickness, friction force, temperature rise, dynamic coefficients, effective damping and stiffness, critical mass, and system characteristic roots have been explored with new conceived bores, and the numerical results have also been compared with conventional plain and conventional pocketed bore bearings. Significant static and dynamic performance improvements have been found in the presence of bionic textures fused micro-pocketed bores in comparison to conventional bores.
