heat flux

Prabin Pradhananga_22497

Hi all,

In this acuTrans manual, I see the following. 

The unit of heat flux should be W/m2. Just curious, what the above gives when I integrate it over a surface using UDF? I want to extract total heat using the above. Am I doing it correctly using the above ?

 

Thanks and  regards,

I think your interpretation is correct. 

AcuProbe also lists the unit of integrated heat_flux as "W" (watts)

I would also agree.  The 'q' in the acuTrans docement equation above is the nodal value - W/m^2.  When we integrate that over the area we get W/m^2 * m^2 - leaving W for the units of the surface integrated heat flux.  That surface integrated heat flux is the quantity used in the user functions for UDF_OSI_HEAT_FLUX.

Thank you, so it is surface integrated heat flux.
