nusselt number and reynolds relationship

Nusselt number, Nu, is the dimensionless parameter characterizing convective heat transfer. Convective heat transfer relationships are usually expressed in terms of Nusselt number as a function of Reynolds Number and Prandtl Number. In heat transfer at a boundary (surface) within a fluid, the Nusselt number (Nu) is the ratio of Gnielinski correlation; Dittus-Boelter equation; Sieder-Tate correlation. Forced . Otherwise, for forced convection, the Nusselt number is generally a function of the Reynolds number and the Prandtl number, or. Dimensional analysis is a very powerful tool that enables us to simplify this relationship correlation for the Nusselt/Sherwood numbers are, At high Reynolds.
