Abstract: A two-dimensional computational fluid dynamics (CFD) model was developed to study the load-bearing capacity of asymmetric texture under the state of fluid lubrication. The effects of asymmetric parameterHand the Reynolds numberReon hydrodynamic load-bearing capacity of the oil film were discussed. It was found that a decrease in asymmetric parameterHmay significantly improve the load-bearing capacity, but an increase in Reynolds numberRemay reduce this effect. For example, with aReat 20, the load-bearing capacity increases by 73.44% with theHvarying from 4 to 0.2. However, with aReat 160, it has only an increase of 4.68% at the same conditions. In addition, the numerical results also showed that the load-bearing capacity will increase with the increase ofRein certain texture.
