Section 8: Nucleate Pool Boiling
Tw = temperature of heating surface
Ts = saturation temperature
Heat transfer at ambient pressure:
 | (Stephan and Preuber) | Eq. (37) |
' saturated liquid
'' saturated vapor
Bubble departure diameter 
Angle ?0 = ?/4 rad for water = 0.0175 rad for low-boiling liquids = 0.611 rad for other liquids
For water in the range of 0.5 bar < p < 20 bar and 104 W/m2 <
< 106 W/m2 the following equation may be applied:
 | (Fritz) | Eq. (38) |
