Air-coolers
Air-coolers
(OP)
Hello,
I have several piping analysis under way for air-cooler inlet and outlet piping systems. I have tried all sorts of configurations to try and model in the most realistic way the connections between piping and the air-coolers and the restraints, but I have yet to come up with something that gives me realistic results (compliant to API 661 or not).
If someone knows how to model air-cooler piping systems successfully, some help would be greatly appreciated.
Thank you.

RE: Air-coolers
If your model of the cooler (pretending it is a big pipe) is not sufficiently accurate, get the nozzle stiffnesses from the vendor, and use this data as "restraint stiffnesses" at the nozzles. Use a CNODE here so that you can define the displacements of the nozzle (again acquired from the vendor).
