Design of shell-and-tube spiral baffle heat exchangers
Thread Content
May I ask about the design method for shell-and-tube spiral baffle heat exchangers? It’s difficult to find design formulas for this type of new heat exchanger. Saturated steam flows in the shell side, while water flows inside the tubes; the unit is vertical. How can the external condensation heat transfer coefficient be calculated, and how should the pitch be determined?
The steam condenses; there is no need to use spiral baffles
Why is it not necessary to use spiral baffles? I’ve heard that spiral baffles can improve the overall heat exchange efficiency
