Nucleate_Boiling_Cooper

 

 

The function Nucleate_Boiling_Cooper(Fluid$, T_sat, T_w, R_p) returns the surface heat flux for nucleate boiling of a fluid.  This correlation is presented in Chapter 11 of Ghiaasiaan (2008) and is based on the work of Cooper (1984).

 

Inputs

Fluid$ - string variable representing a fluid/vapor (i.e., a Real Fluid) in the EES data base.

T_sat  -  the saturation temperature of the boiling liquid in  [C], [K], [F], or [R].  

T_w - the temperature of the surface in [C], [K], [F], or [R].  

R_p - surface roughness [m] or [ft].  If R_p<0 then the default value of R_p is used (R_p = 1 micron).

 

Notes:

This procedure is responsible for determining the property data of the specified fluid and implementing the correlation. The Kutateladze correlation is also available in EES as Nucleate_Boiling_Kutateladze. The Rohsenow and Gorenflo correlations are also available.

 

Example:

$UnitSystem SI Mass J Pa K

$VarInfo q``_s Units = 'W/m^2'

Fluid$ = 'Water'

P = 1 [atm]*Convert(atm,Pa)

DT = 10 [K]

T_sat = T_sat(Fluid$,P=P)

T_w = T_sat + DT

q``_s = Nucleate_Boiling_Cooper(Fluid$,T_sat,T_w,-999 [m])

 

 

{Solution: 

q``_s=77157 [W/m^2]}
