What is Nusselt Number?

The Nusselt number (Nu) is a dimensionless quantity that characterizes convective heat transfer in fluid mechanics. It is named after the German physicist Wilhelm Nusselt and is defined as the ratio of convective to conductive heat transfer across a boundary.

In simpler terms, it indicates the effectiveness of heat transfer due to convection compared to conduction.A high Nusselt number signifies efficient heat transfer, indicating that convection dominates, whereas a low Nusselt number suggests that conduction is more significant.
