Abstract: | In order to resolve the slow computing speed and limited computing scale of traditional numerical methods for multiscale surface texture hydrodynamic lubrication, the finite cell method (FCM) is proposed. The results of FCM are compared with the conventional FEM, CFD and the existing theoretical and experimental data. A very good agreement of the results is observed. Both the computing time and storage required by FCM are significantly reduced; the computation speed can reach about 18 mega points per minute on the personal computer. Meanwhile, the computational scale is also significant expanded by the aid of FCM. |
