[Bldg-sim] convection coefficient for internal fluw in rectangularduct

[Peter Simmonds]

This takes me back a few years. Yes there is data on the different
output, convective and radiative for different radiators with and
without fins.(if this is what you require?)

I have an old Buderus handbook from about 1980 which has the different
values, I believe Recknagel-Sprenger carries different values. I think I
also have some values in my Masters thesis references, but this would
really be scraping the barrel and would require me taking a trip to the
garage and searching through a dozen carefully ignored archive boxes.

 

Is this what you are looking for?

Subject: [Bldg-sim] convection coefficient for internal fluw in
rectangularduct

 

Dear,

 

could anyone suggest me a correlation for the convection coefficient in
a rectangular duct valid for both laminar and turbulent flow? Or more in
particular I'm looking for a convection coefficient that describes the
effects for the hollow space in beteen two panels of a panel radiator
with convecter blades (type 22 radiator).

 

Thanks a lot!
