Wall Heat Flux unit
 
Hi,

According to CFX-5 Reference Guide, the unit of the wall heat flux in CFX-5.6 is kg/s^-3 and the unit of the heat transfer coefficient is kg/s^-3 K. Can this really be correct?

Hi Marta-Karin

Strictly speaking, they are correct:

Heat Flux = W m^-2 = (kg m s^-2 x m s-1) x m^-2 = kg s^-3

HTC = W m^-2 K = kg s^-3 K

but not very useful to anyone. Perhaps CFX should employ some engineers instead of computer scientists.
