文摘
- •
A mathematical model of floating LNG SWHEs under rolling conditions is developed.
- •
A model of mass flow rate distribution at arbitrary tilt angles is established by computing three-dimensional mass transfer among adjacent control volumes.
- •
A heat transfer model for gas and liquid rich regions is developed, capable of reflecting the influence of tilt on the performance of SWHEs.
- •
An overall alternative iterative algorithm is developed to solve the equations of the presented model.
