Nucleate Boiling_Kutateladze
The function Nucleate_Boiling_Kutateladze(Fluid$, T_sat, T_w) returns the surface heat flux (q``_s) for nucleate boiling of a fluid by means of a heated surface of a specified material. This function is presented in Section 7.3.2 of Barron and Nellis (Cryogenic Heat Transfer, 2nd Edition, 2016, CRC Press).
Inputs
Fluid$ - 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].
Notes:
This procedure is responsible for determining the property data of the specified fluid. It uses the correlation developed by Kutateladze (1952). (Kutateladze, S. S., 1952. Heat Transfer in Condensation and Boiling, 2nd ed. Moscow: State Science and Technology Publications of Literature on Machinery.)
The Rohsenow correlation is also available in EES as Nucleate_Boiling_Rohsenow.
Example:
$UnitSystem SI J K Pa Mass
$VarInfo T_w units=K
T_sat=100 [K]
DT=6 [K]
T_w=T_sat+DT
Fluid$='Oxygen'
q``_s= nucleate_boiling_kutateladze(Fluid$, T_sat, T_w)
{Solution:
q``_s=47,309 [W/m^2]}
