Performance of non-recessed hole-entry hybrid journal bearing operating under turbulent regime

The effect of turbulent flow on non-recessed hole-entry hybrid journal bearing system has been investigated numerically. For turbulent flow of lubricant in compensated hole-entry hybrid journal bearing by CFV, the Reynolds equation has been modified and solved using finite element method. The performance characteristics parameters of bearing have been presented for different values of Reynolds numbers. The bearing provides the higher values of minimum fluid film thickness and fluid film stiffness coefficients for constant restrictor design parameter when bearing operates under turbulent regime than laminar regime
