# Plotting the Boiling Curve

Use the tool to plot the boiling curve of water at atmospheric pressure.

From the Quenching ribbon, click on the Boiling
Curve icon to create the boiling curve.

Note: To plot the boiling curve, the model must have an immersion cooling quench
zone.

In the dialog, you can change the parameters for the boiling curve.

- Convection Scale Factor represents the effectiveness of the heat transfer process. A higher convection scale factor implies more efficient heat transfer, leading to faster cooling of the object.
- Nucleate Boiling Exponent M and Nucleate Boiling Exponent N are exponents in Rohsenow correlation for nucleate boiling. Exponent M must be positive value less than 1. Exponent N must be a positive value greater than or equal to 1.
- Surface Factor is a parameter that accounts for the characteristics of the surface undergoing boiling. Higher the surface factor, higher the roughness or the surface area, more efficient will be the heat transfer. Surface factor must be a positive number.
- CHF Scale Factor is a parameter used to predict the Critical Heat Flux. CHF Scale factor generally fall within the range of 0.4 to 4.
- MHF Scale Factor is a parameter used to predict the Minimum Heat Flux. Lower the MHF Scale factor suggests that the Minimum Heat Flux is less affected by the changes in the temperature difference between the surface and saturation temperature of the fluid. MHF Scale factor generally fall within the range of 0.5 and 10.0.
