文摘
- •
A new upper bound of two-phase buffeting forces on tube bundles is developed.
- •
Tube in steam generator under non-uniform two-phase cross-flow is analyzed.
- •
The proposed bound is more conservative than the single-phase based one.
- •
The proposed bound reduces the excessive conservatism of de Langre’s approach.
