FC_Vertical_Channel_ND

 

 

Procedure FC_Vertical_Channel_ND(Ra, LoverS : Nusselt) returns the Nusselt number in a rectangular open vertical channel through which a fluid is flowing by free convection as described in section 6.2.5 of Nellis and Klein.  See FC_Vertical_Channel for a dimensional correlation for this geometry.

 

Inputs:

Ra - Raleigh number [ ] based on S, the channel spacing

LoverS - ratio of the height (H) to the channel spacing

 

Outputs:

Nusselt - Nusselt number [-]

 

Notes:

 

The correlation is from Elenbaas (1942)

 

Example:

Ra=1e6

LoverS=10

Call fc_vertical_channel_nd(Ra,LoverS:Nusselt)

 

{Solution: 

Nusselt=10.66}
