Dear to all

 

Would you be so kind as to clarify, what is meant by the term "No. of Crosspasses" on Data Sheet of Heat Exchanger

 

Is this term related with the number of baffles perpendicular to the flow?

 

Thanks very much

Crosspasses is a term that HTRI uses. It identifies the different characteristics of baffles.

[SASU]

No. of Crosspasses = No. of baffles + 1

[Pilesar]

As the fluid travels through the shell side of a shell and tube exchanger, it passes nominally perpendicular across the tube bundle because the baffles partially block the flow. The fluid changes direction when it gets to the other side of the baffle and travels perpendicular to the tubes in the opposite direction. Each time the fluid passes perpendicular to the tube bundle is a crosspass.

Yes, cross pass and baffles are related to each other. Crosspass count is higher by 1 over the baffle count.
