| Popis: | A mathematical model is established based on a modified Reynolds equation in polar coordinates, and solved by the multi-grid method to demonstrate the performance of micro-texturing mechanical seal surface. Sample cases of cylinder-shaped, square-shaped and diamond-shaped micro-asperity are studied to show the performance of micro-texturing mechanical seals. The results show that geometry has a vital influence on the friction coefficient and leakage. Diamond-shaped micro-texturing asperities have better performance than the others. And the performance is sensitive to the area density than the micro-texturing depth. The numerical approach can be a useful engineering tool, analyzing and optimizing the performance of micro-texturing mechanical face seals. |
