Heat Transfer in Fluidized Bed
 

Hi there

Maybe for those who've been read ANSYS (ver. 15.0) documentation about Tutorial Guide Chapter 25: Using the Eulerian Granular Multiphase Model with Heat Transfer could help me..

There's an equation for calculating ave_htc:
ave_htc = -k_mix*(t_mix-373)/(58.5*10^(-6))/80

I wonder, where does this ave_htc equation came from???
Could someone tell me the basic equation for this ave_htc equation?

Any help would be nice :)

Thanks
