The thermal boundary layer is a region where:

The thermal boundary layer is a region where: Correct Answer Convection and dissipation terms are of the same order of magnitude

Concept:

The thermal boundary layer is generated as a result of molecular momentum and thermal diffusivity.

In the thermal layer, convection and dissipation are of the same magnitude.

Convection and conduction cannot be of the same magnitude as convection takes place due to the combined effect of conduction and momentum.
