Novel Biomimetic Texture and Experimental Validation Based on CFD
This paper addresses the challenge of zirconia ceramic components gradually failing to meet the demands of new high-strength working conditions.To tackle this issue,three biomimetic profiles are extracted from biological surfaces.Employing a combined approach of numerical simulations and experiments,the impact of biomimetic surface shapes,texture angles,and arrangement on friction reduction performance is thoroughly investigated.The simulation results highlight that regions with asymmetric pressure distribution and larger negative pressure exhibit superior oil film bearing capacity.Among the examins configurations,the fish scale texture,a texture angle of 270°,and the">"texture arrangement exhibit more significant negative pressure regions and higher oil film bearing capacity,leading to optimal friction reduction performance.Experimental results corroborate the simulation findings,demonstrating the consistent achievement of the lowest friction co-efficients by the fish scale texture under various working conditions.
