Hi,

The linearization here simplifies the incorporation of radiation effects within the overall heat flux calculation. The CAF enhances the convective heat transfer component based on the difference between the measured and ideal Nusselt numbers, indicating the effectiveness of the convection. Convective heat transfer is inherently dependent on the temperature difference between the fluid and the surface. Hence, the CAF modifies the temperature-dependent component of the heat flux to account for enhanced or diminished convective effects.

Thank you.
