[TRNSYS-users] Convection in type 534 and inversion mixing flowrate

[Jeff Thornton]

<I am facing a problem with the convection in type 534. I read the
documentation but I still don't understand few things.
Can somebody
explain me the behaviour of this type when the parameter inversion
mixing flowrate is equal to 0 ?> 

When the inversion flow rate is set
to zero, temperature inversions in the tank are not rectified and the
system can remain in that state (hotter beneath colder). If the
inversion flow rate is set to a positive, non-zero number, the nodes
involved in the inversion will be mixed at the specified flow rate
(inversions dissolve over time). If the inversion flow rate is set to a
negative, non-zero number, the nodes involved in the inversion are
immediately mixed at the end of every timestep through an internal
mixing process to eliminate any temperature inversions.
