Abstract

This study deal with the numerical simulation of a hybrid double layer conical porous bearing (DCPB) considering the synergistic effects of a double layer porous matrix and non-Newtonian lubricant (cubic law model) behaviour. The present study investigates the interactive effects of the non-linear factor of lubricant, permeability parameter and semi cone angle on the performance of a hybrid DCPB. The modified Reynolds equation is solved using the finite element technique for a hybrid DCPB. Findings of this study indicate that the DCPB improve the performance parameters as compared to hybrid single layer conical porous bearing (SCPB). Further, the use of non-Newtonian lubricant improves the stability threshold speed margin ω̅th and reduces the frictional power loss (p̅fric).
