We recently finished up a round of additions of secondary flow
modeling capabilities for our general-purpose thermohydraulic
analyzer, SINDA/FLUINT. We ended up with just the Martin-type equation
as a built-in feature, but we had looked into NASA's KTK code
(knife-to-knife) as a more elaborate 1D option:
http://gltrs.grc.nasa.gov/reports/2005/CR-2003-212367.pdf
We ended up deciding just to use KTK's outputs as inputs to our
system-level code instead of trying to embed all of that into a
commercial code, since the demand is pretty specialized. But I know
you can get the KTK code and documentation from NASA, though there
might be export restrictions.

Post by David Kelsall (Plus Net)Hi,
My colleagues and I are trying to model various types of labyrinth seals for
gas turbines. Does anyone know of some simple one- or two- dimensional
modeling equations in addition to the Martin equation - which we already
have.
Thanks,
David Kelsall
