Which outcome occurs in supercritical fluids when the Prandtl number approaches unity?

💡 Explanation

As the Prandtl number approaches one, the momentum and thermal diffusivities are nearly equal, therefore heat transfer dramatically improves because thermal boundary layers remain efficiently removed from the heat source, rather than insulating it.
