| Abstract: | A representative unit duct model of the shell side in the rod baffle heat exchanger was presented.It is more convenient and efficient to simulate the complicated shell and tube heat exchanger with the unit duct model.Numerical analyses obtained the detailed distribution information of the flow field,pressure field and temperature field in the unit duct in the center region of the shell side of the rod baffle heat exchanger,which provide the theoretical basis for optimizing the structure and analyzing enhanced heat transfer mechanism of the rod baffle heat exchanger. |
