udf for additional pressure loss coeffizient in pipes (zeta value)
 
1 Attachment(s)
Hello,

i tried to simulate a closed system with natural cirulation. The geometry is shown in the attached picture. The simulation works and now i am trying to inclued a additional pressure loss coeffizient (zeta-value) between the absorber (red) and the cooler (blue) in order to reproduce reality better.
Does anybody know if (and how) there is a possibillity to include an additional pressure loss coefficient as a UDF instead of redrawing the geometry for each value of pressure loss coeffizient. Thanks!

Does anybody have an idea how to solve this?

Hi Claudia,
did you solved the problem because I have a similar problem?
