Wilhelm Nusselt was a German engineer and physicist known for his contributions to the field of heat transfer. He is best known for developing the Nusselt number, a dimensionless quantity that characterizes convective heat transfer in fluid mechanics. The Nusselt number is particularly useful in determining how effectively heat is being transferred from a solid surface to a fluid or vice versa.
