modeling internal frame cavities

[marta marrone]

Hi,

I’ve some doubts about modeling frame cavities as per procedure indicated at the paragraph 6.3.6 of NFRC Simulation Manual (July 2017).

The procedure (page 6-11;6-2) explain the passages to divide the larger frame cavity into smaller frame cavities observing the Nusselt number.

Sholud I first divide the bigger throat, if necessary divide all horizontal throats and definitely (if necessary) all vertical throats (less than or equal to 0.20 inches) to limit the Nusselt number less than or equal to 1.2?

Is it correct?

 

Thanks,

Marta
