htri calculation problem assistance
Thread Content
During the calculations, when I simply changed the direction of the baffle cuts from horizontal to vertical, the issue of an excessively high flow velocity at the shell inlet arose. Could you tell me why this happened?
Why isn’t anyone answering? Is the forum I posted in the wrong one? Thank you very much for your reply.
This is easy to understand, right? If you have a horizontal heat exchanger and change it to a vertical one, the flow velocity will definitely increase. In a horizontal configuration, due to gravity, the fluid near the bottom of the baffle has difficulty flowing. Similarly, in the case of a vertical heat exchanger or when dealing with gases, this impact is relatively smaller compared to that of liquid flow.
Reply to 3# lsrwan: What I’m referring to is the direction of the cuts on the baffle plates; how could this affect the flow velocity at the inlet of the housing?
