文摘
- •
Two phase flow and heat transfer in double pipe evaporator is studied computationally.
- •
Eulerian two-fluid framework in conjunction with RPI wall-boiling model is validated.
- •
Relatively greater vapor generation upstream benefits parallel flow configuration.
- •
Flow of FC-72 in the tube-side results in higher vapor generation for cases studied.
- •
Net heat transfer effectiveness of parallel flow is about 6% higher than counter flow.
