CFD - Opis:
- Rotordynamic characteristics of a high temperature sodium liquid (HTSL) seal were studied in this paper by using CFD software. Compared with the water liquid seal, the HTSL seal has a larger leakage flow rate and a lower drag power loss. The HTSL seal has a larger direct stiffness coefficient and the effective stiffness coefficient Keff is also larger than the water liquid seal, which means the HTSL seal has a better stiffness capacity. The HTSL seal possesses a positive effective damping coefficient Ceff in the whole whirling frequency range, which means better stability for the rotor system especially in high rotor speeds.
