- •
A dynamic model for FLNG spiral wound heat exchanger with multiple phase-change streams is developed.
- •
A matrix-based method to describe the heat transfer relations among the phase-change streams is developed.
- •
A theory-based model to calculate the heat transfer among the phase-change streams is developed.
- •
An implicit iterative algorithm to solve the equations of the dynamic model is proposed.
- •
The sloshing-induced reduction of SWHE overall performance is within 5% for most cases.
