Card 9 - RELTEMP Relative Temperature Correction

KODE

KODE is the code RELTEMP (or 85)

N1

N1 is an element number or group name to which relative temperature correction will be applied.

T1

T1 may be:

• a constant relative temperature correction.
• of the format Tn (e.g. T5), where n is a table number referencing a table whose dependent variable is TEMP.
• of the format En (e.g. E5), where n is an expression number referencing EXPRESSION card.

Code example

$ A relative temperature correction of 5.5 is applied to element 200.
RELTEMP 200 5.5
$ A relative temperature correction of 7.0 is applied to the elements
$ of group GROUP1.
RELTEMP GROUP1 7.0

Notes

The T1 field will be used to calculate relative temperature correction ΔT for all elements in N1. If a given element has a nonzero ΔT, then in the heat balance equations in the Analyzer solve, all the RELTEMP card relevant heat flows will use that element temperature shifted by ΔT, i.e. taking T+ΔT instead of T. The relevant heat flows include heat flows through convective thermal couplings as well as through all couplings between hydraulic elements and non-hydraulic elements.

Relative temperature corrections are typically used in rotating machinery applications.
