| Abstract: | The main value range spiral-wound structural parameters and LNG heat exchanger are introduced. The calculation of various parameters of spiral wound layer is theoretically derived. The calcu- lation methods of flow clearance, circulation area and equivalent diameter at the shell side are summarized. The calculated data for the flow clearance and circula- tion area in different formulas are compared. The use principle of the calculation formulas for the flow clear- ance and circulation area is given. |
