Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Nusselt number, abbreviated as Nu, a dimensionless number, describes the ratio of convective heat transfer to conductive heat across a boundary.

Nusselt number formula

\(\large{ Nu=\frac{h \; l_c}{k}   }\)   


\(\large{ Nu }\) = Nusselt number

\(\large{ l_c }\) = characteristic length

\(\large{ h }\) = heat transfer coefficient

\(\large{ k }\) = thermal conductivity
